Since the transferred oxygen atom carries a positive charge, peracids must be considered electrophilic oxidizing agents.In the laboratory, the epoxidation agent of choice is m-chloroperbenzoic acid (MCPBA). is remarkably selective toward aliphatic cis-olefins. Acetic acid is the principle component of vinegar. In the presence of organic matter, 200 to 500 ppm is required. 125, 5250-5251. This equilibrium solution is the substance sold 36 . In a recent study, peracetic acid at 30 mg l−1 was shown to be more efficient than 250 mg l−1 of sodium hypochlorite at removing biofilm cells of S. aureus from stainless steel and polypropylene surfaces. Different doses of sterilant are needed to be effective against each of these organisms. Gnotobiotic facility personnel are advised to work with their institutional environmental health and safety personnel regarding the use of aerosolized sterilants. diastereoselectively. 37 . The system exhibits broad substrate scope and iodine compounds uses peracetic acid as an oxidant. J. Fisher, in Encyclopedia of Food Sciences and Nutrition (Second Edition), 2003. Properties: Peracetic acid is a mixture of acetic acid (CH3COOH) and hydrogen peroxide (H 2O2) in an aqueous solution. Peracetic acid is an organic acid generated by reacting acetic acid and hydrogen peroxide. Peracetic acid is not considered a carcinogen by the Environmental Protection Agency, Occupational Safety and Health Administration, or the National Toxicology Program, and it is not genotoxic or mutagenic (Malchesky, 2001), although it can be a tumor promoter. Several commercial formulations are available. Simulated-use trials with the earlier version of this processing system have demonstrated excellent microbicidal activity,74,158-161,162 and three clinical trials have demonstrated both excellent microbial killing and no clinical failures leading to infection.163-165 Three clusters of infection using the earlier version of the peracetic acid automated endoscope reprocessor were linked to inadequately processed bronchoscopes when inappropriate channel connectors were used with the system.166,167 These clusters highlight the importance of training, proper model-specific endoscope connector systems, and quality control procedures to ensure compliance with endoscope manufacturer's recommendations and professional organization guidelines. 77, 1610-1615. Nonetheless, Peris et al. Occupational exposure to peracetic acid may occur through inhalation and dermal contact with this compound at workplaces where it is produced or used. It is suitable for CIP, as it is nonfoaming. using peracetic acid as oxidant. Kang, L. H. Gade, J. Org. Proteins that adsorb to the membrane after each blood contact are fixed and can continuously accumulate within the membrane pore structure to increase the resistance to transmembrane transport of middle molecules. Peracetic acid is formed in the environment through a series of photochemical reactions involving formaldehyde and photo oxidant radicals. Lett., 2008, 10, 2095-2098. In addition, carbamate moiety of the substrates plays a key role in asymmetric induction interacting with the catalyst through a hydrogen bond. Hydrogen peroxide has been previously recommended by the NOSB for the National List in processing (synthetic, allowed at Austin, 1995). These are composed of two parts, a base solution of sodium chlorite and an acidic activator, which are combined and mixed with water immediately before application to form a solution of chlorous acid and chlorine dioxide. Promox S.p.A. The PAA solution was kept at 70° F throughout the test Peracetic acid can corrode copper, brass, bronze, plain steel, and galvanized iron, but these effects can be reduced by additives and pH modifications. This reaction was used for the quantitative iodometric determination of total peroxide in procedure B. H2O2 reacted with potassium permanganate in acid medium, but peracetic acid did not react under the same conditions. Mechanistic studies It is efficient in removing biofilms and works well at colder temperatures. Peroxyacetic or peracetic acid (PAA) is produced from the reaction between hydrogen peroxide and acetic acid. Spor-Klenz™ (Steris Life Sciences), a ready-to-use sterilant solution containing 1% hydrogen peroxide and 0.08% peracetic acid, has broad sporicidal efficacy and completely inactivates Mycobacterium spp. Other products combining peracetic acid and hydrogen peroxide are available, as noted below. Chem. Reprocessing using peracetic acid (without bleach) causes a decrease in the removal of middle molecules by high-flux dialyzers as the number of reuses increases. Formulated and stored properly, it can be stable for a year or more. The complex [MnII(R,R-mcp)(CF3SO3)2] Du Bois, T. D. P. Stack, Org. In solution, peracetic acid dissolves and forms back acetic acid and hydrogen peroxide. A. Y. Koposov, R. R. Karimov, A. Trenton R. Schoeb DVM, PhD, DACVP, Richard J.

Peracids such as peracetic acid and mCPBA are common stoichiometric oxidants frequently used in olefin epoxidation. Steriplex™ SD (sBioMed) is a two-part product utilizing silver, peracetic acid, and ethanol (0.015%, 0.15%, and 10%, respectively, in the activated product). Peracetic acid and H2O2, as oxidizing agents, reacted with potassium iodide in an acid medium, evolving iodine. This technique is to be used to sterilise instruments immediately prior to use; there is no storage of devices sterilised by this method. In our view, using standard laboratory tests to compare products well established to be effective sterilants when properly used is of far less value than determining that a sterilant’s applications – that is, the procedures in which it is used – are effective and reliable. It’s a broad-spectrum biocide with a fast reaction time (minutes rather than hours), and leaves no harmful by-products. Chem., 2006, After mixing acetic acid and aqueous hydrogen peroxide solution, the reaction to form equilibrium peracetic acid can proceed in any desired container. There is a large volume of literature on testing liquid sterilant and disinfectant procedures in health care and food processing; unfortunately, however, there is little information regarding comparative effectiveness or standardized testing as applied directly to gnotobiotics. William A. Rutala, David J. Weber, in Mandell, Douglas, and Bennett's Principles and Practice of Infectious Diseases (Eighth Edition), 2015. Domínguez-Henao et al., [24] Organisms on surfaces are almost always more difficult to kill than those in suspension (Berube et al., 2001; Gibson et al., 1995; Sagripanti and Bonifacino, 1999, 2000; Springthorpe and Sattar, 2005; van Klingeren et al., 1998), and, in surface tests, different materials can yield different results (Thorn et al., 2013). Chlorine dioxide in liquid form is now the most commonly used sterilant in gnotobiotics. 79-21-0] CH3–CO–OOH Synonyms: Peroxyacetic acid Ethaneperoxoic acid 1mL/m3 (ppm) ¼b 3.16 mg/m3 Peracetic acid (PAA) is acolourless liquid with apungent odour (molar mass 76.05 g/mol, boiling point 105°C (40% solution in glacial acetic acid), melting point 0.1°C, vapour pressure 14.32 hPa at 20°C). Although this product is rapidly effective against a broad range of microorganisms,168,169 it tarnishes the metal of endoscopes and is unstable, resulting in only a 24-hour use life.169, M. Mikhail, T. Young, in Decontamination in Hospitals and Healthcare, 2014. This activity is fast and is maintained at temperatures lower than ambient. These qualities make it ideal for use in many industries such as food and beverage, health care, Due to its mild conditions, this method is suitable for a It is sold as a disinfectant, not a sterilant, for hospital and other applications. Peroxyacetic, or peracetic, acid was the first germicide used to sterilize isolators and is still used because of its effectiveness, low cost, and compatibility with most plastics. Combining peracetic acid with hydrogen peroxide results in synergistic antimicrobial activity (Block, 2001). (X = Cl, Br) in the presence of environmentally benign hydrogen peroxide (H2O2) Other liquid sterilant and ‘high-level’ disinfectant products include Actril™ (0.08% peracetic acid and 1.0% hydrogen peroxide; Mar Cor Purification), Cidexplus™ 28-Day Solution (3.4% glutaraldehyde; Johnson & Johnson), Minncare™ (4.5% peracetic acid and 22.0% hydrogen peroxide; Minntech BV), PeridoxRTU™ (4.0–4.8% hydrogen peroxide and 0.17–0.29% peracetic acid; Contec Inc.), Vimoba™ (chlorine dioxide; Quip Laboratories), Sanosil S010™ (5% hydrogen peroxide and 0.01% silver nitrate; Sanosil International), Sporgon™ (7.35% hydrogen peroxide and 0.23% PAA; Decon Laboratories), and Wavicide-01™ (2.65% glutaraldehyde; Medical Chemical Corporation). Peracetic Acid Reaction. step. The probable routes of peracetic acid are eye, dermal, inhalation, and ingestion. Methods we use are described in relevant places in this chapter. subtracting the concentration of H2O2 from the total peroxycarboxylic acid concentration. 0 0. Peracetic acid (PAA) is increasingly used as an alternative disinfectant and its advanced oxidation processes (AOPs) could be useful for pollutant degradation. Sampling Solutions for Peracetic Acid . by employing a system comprising of sub-stoichiometric amounts of TiX4 Soc. It has been Peracetic acid (PAA) has been widely used with thin tissues such as the small intestinal submucosa (SIS) and urinary bladder matrix (UBM) in conjunction with mechanical methods for decellularization. In our tests, Steriplex™ SD killed Geobacillus stearothermophilus 106 spore strips in 10 min and Bacillus atropheus 106 strips in 30 min. Peracetic acid comes in an equilibrium solution with H 2 O 2 water, and acetic acid. 8 years ago. A palladium-catalyzed diacetoxylation of alkenes in the presence of peracetic 35 containing peracetic acid, acetic acid and hydrogen peroxide. A facile ruthenium-catalyzed methodology for the preparation of pentavalent peracetic acid has been shown2-4 to occur in two phases: an initial, basically instantaneous decrease; followed by a slow decomposition. This initial decrease in PAA is due to an oxidant demand, resulting from reactions with transition metals, suspended and dissolved solids, and organic species within the wastewater. disclosed a highly enantioselective tripeptide catalyst 96, and established a unique carboxylic acid/peracid catalytic system using a carbodiimide technique, which is utilized in a peptide synthesis to activate carboxylic acids (Scheme 47).160 The carboxylic acid function of the N-terminal aspartate residue is the reaction site and a folded secondary structure constructs a suitable environment for the stereocontrol. However, in our hands it did not neutralize Steriplex SD™. Peracetic acid [CAS No. Reproduced from Peris, G.; Jakobsche, C. E.; Miller, S. J. J. The reaction offers remarkable oxidant efficiency. after 20 min of contact time at 20°C (Rutala et al., 1991). And perhaps a bit of oxygen from the hydrogen peroxide decomposing. Source(s): https://shrinkurl.im/a7Wfm. A contact time of 1 h is recommended. internal, enones, and methacrylates using peracetic acid as the terminal Amino acids are important components in targeted foods for PAA treatment and ubiquitous in natural waterbodies and wastewater effluents as the primary form of dissolved organic nitrogen. reaction is accompanied by a sharp colour change. Peracetic acid (PAA) is an oxidizer widely used for the sterilization of equipment in hospitals, pharmaceutical, cosmetic and food industries and also for water and wastewater disinfection. 79-21-0), also known as peroxyacetic acid or PAA, is an organic chemical compound used in numerous applications, including chemical disinfectant in healthcare, sanitizer in the food industry, and disinfectant during water treatment. Corrosive Effects of Peroxyacetic Acid Experimental Methods: Corrosion coupons of the various metals were suspended in the various concentrations of PAA for 30 days. Peracetic acid (PAA) is a sanitizer with increasing use in food, medical and water treatment industries. Peracetic acid is presently utilized in several sterilization procedures. A processing system using peracetic acid at a temperature of 50° C to 56° C can be used for processing heat-sensitive semicritical and critical devices that are compatible with the peracetic acid and processing system and cannot be sterilized by other legally marketed traditional sterilization methods validated for that type of device (e.g., steam, hydrogen peroxide gas plasma, vaporized hydrogen peroxide). Peracetic acid is an equilibrium mixture of acetic acid and hydrogen peroxide and water CH3COOH + H2O2 ↔ CH3COOOH + H2O. 38 Peracetic acid is an unstable oxidizing agent, which is why it is such an effective sanitizer. triazacyclononane exhibits high catalytic activity in epoxidation reactions point toward an electrophilic oxidant delivering the oxygen atom in a concerted Peracetic acid is produced by a reaction between hydrogen peroxide and acetic acid. Peracetic acid is an organic acid generated by reacting acetic acid and hydrogen peroxide. acids in good to high yields. Peracetic acid solution should always be prepared immediately before use, because it loses about half of its strength within 24 h. Thirty minutes of contact time is sufficient. It remains effective in the presence of organic matter and is sporicidal even at low temperatures. This can be done by use of dilution techniques, neutralizing media, or combinations of these. Reaction principle. It is available from laboratory chemical suppliers as a liquid containing 40%, Jeng and Woodworth, 1990; Knapp and Battisti, 2001; Orcutt, Methods and Complications of Dialyzer Reuse, Paweena Susantitaphong MD, PhD, Bertrand L. Jaber MD, MS, in, Handbook of Dialysis Therapy (Fifth Edition), Synthetic Methods IV – Asymmetric Oxidation Reduction, C–N. Peracetic acid may attack plant materials, such as rubber gaskets, and at higher concentrations, corrosion may be a problem. Peracetic acid is finding application across the food spectrum from dairy to produce to meat processing and is being increasingly adopted. or peracetic acid (MeCO3H) as the oxidants. We are not aware of reports of evaluation of any of these products for use in gnotobiotics. Peracetic acid was introduced in 1955. For viruses the dosage range is wide (12 to 2250 ppm), with poliovirus inactivated in yeast extract in 15 minutes with 1500 to 2250 ppm. For the decontamination, disinfection, or sterilization of products, such as isolators and vapor-phase producers, peracetic acid was used. Since the reaction has a low heat of reaction, the reaction can proceed without cooling and even adiabatically. It can be corrosive to some metals, including copper, brass, bronze, steel and galvanised iron, so it must be combined with additives to reduce this effect. This method enables also oxidative lactonizations of unsaturated carboxylic Optimal sporicidal activity in the vapor phase is achieved at 80% relative humidity. Peracetic acid (PAA) is one of the most versatile and widely used disinfectants on the market. Peracetic acid is a highly reactive material. Company, X. Fontrodona, X. Ribas, M. Costas, Org. It is 1075 times more sporicidal in the gaseous state than ethylene oxide (Jeng and Woodworth, 1990). However, sporocidal activity was minimal against spores adhering to stainless steel without the presence of an aqueous suspension. 711, 717 An automated machine using peracetic acid to sterilize medical, surgical, and dental instruments chemically (e.g., endoscopes, arthroscopes) was introduced in 1988. Personnel using peracetic acid should wear gloves, disposable clothing, and a full-face respirator with chemical filter cartridges. However, an advantage to using peracetic acid is that the liquid sterilant is able to flow through narrow lumens in endoscopes and sterilise them. Peracetic acid (C 2 H 4 O 3) is a mixture of acetic acid (CH 3 COOH) and hydrogen peroxide (H 2 O 2) in a watery solution.It is a bright, colourless liquid that has a piercing odour and a low pH value. The equilibrium constant is 0.37 at room T Highyieldsigh yields canbeachievedwithcan be achieved withuptoup to 10 days 19 R. Akula, M. J. Galligan, H. Ibrahim, Synthesis, 2011, Peracetic, or peroxyacetic acid, is characterized by a very rapid action against all microorganisms. Peracetic acid is a very effective biocide but it quickly reacts in the environment to break down to harmless byproducts. 347-351. Dey–Engley neutralizing broth works well with chlorine dioxide and peracetic acid sterilants (Espigares et al., 2003; Sutton et al., 2002; Terleckyj and Axler, 1987). commercially available peroxyacids as the oxidants is catalyzed by triflic acid. Peracetic acid has a wide antimicrobial spectrum, which includes bacterial spores and viruses. By continuing you agree to the use of cookies. The Fenton-type reaction of 52 μmol L –1 PAA with Fe 3+ ions exhibited the highest degradation efficiency of the dye (98.98 ± 0.38%) after 30 min of treatment, whereas in the reaction of H 2 O 2 with Fe 3+, the degradation efficiency was 90.10 ± 7.25% after the same period. Before answering the question, just a few comments about peracetic acid. and engineering controls such as exhaust air to scavenge chemical vapors away from personnel. C.P. A major advantage of peracetic acid is that it is effective in vapor and liquid phases (Block, 2001; Trexler, 1984). The STERIS System 1E (STERIS Corporation, Mentor, OH) automated system uses peracetic acid diluted in sterile water to rapidly sterilise devices in 20–30 minutes. preparation of iodylarenes bearing strongly electron-withdrawing groups. The material is supplied as an equilibrium mixture: It is soluble in water and is completely biodegradable, breaking down to harmless products: As supplied, peracetic acid is corrosive and has a very irritating smell, similar to vinegar; because of these properties, it is unpleasant to handle, and manual use is not recommended. K. Matsumoto, T. Katsuki, in Comprehensive Chirality, 2012. It is highly effective against all microorganisms, and, like peracetic acid, is effective in both gaseous and liquid phases (Jeng and Woodworth, 1990; Knapp and Battisti, 2001; Orcutt et al., 1981; Pell-Walpole and Waller, 1984). Peracetic acid will inactivate gram-positive and gram-negative bacteria, fungi, and yeasts in less than 5 minutes at less than 100 ppm. It is available from laboratory chemical suppliers as a liquid containing 40% peracetic acid. A work hazard assessment should be conducted to implement the use of the appropriate personal protective equipment (chemical respirator, gloves, goggles, face shield, etc.) In the market, it exists as a 35% or 40% solution. This is a somewhat nasty compound. The end point of the reaction is accompanied by a sharp colour change. As an in-use solution, it is not very stable and will react with organic materials. Scheme 47. scope of olefins including terminal, tertiary, cis and trans A special advantage of peracetic acid is its lack of harmful decomposition products (i.e., acetic acid, water, oxygen, hydrogen peroxide); it enhances removal of organic material155 and leaves no residue. Peracetic acid is corrosive, and it is irritating to the eyes, skin, and respiratory tract. Co(II) or Co(III) can activate PAA to produce acetyloxyl (CH3C(O)O•) and acetylperoxyl (CH3C(O)OO•) radicals with little •OH radical formation, and Co(II)/Co(III) is cycled. Shruti Moondra, ... Rakesh K. Tekade, in Dosage Form Design Parameters, 2018. It’s environmentally-friendly as it hydrolyzes to acetic acid and hydrogen peroxide in water. at 0 °C in <5 min. Indeed, elongation of the carbamate tether and elimination of the carbamate moiety lead to almost complete loss of asymmetric induction. I. Garcia-Bosch, A. Aspartate-catalyzed asymmetric epoxidation. It is thought to act as an oxidising agent, denaturing proteins and disrupting cell walls. It is effective at low concentrations and temperatures, and, in liquid form, in the presence of organic matter, although it does not penetrate parasite cysts and arthropod eggs (van der Gulden and van Erp, 1972). Peracetic acid, which is soluble in water, has a pungent odor and is a colorless liquid. Expired - Lifetime In solution, peracetic acid dissolves and forms back acetic acid and hydrogen peroxide. Chauret, in Encyclopedia of Food Microbiology (Second Edition), 2014. The advantages, disadvantages, and characteristics of peracetic acid are listed in Table 301-2. acid and acetic anhydride produces diacetates efficiently and Via A.

Chemische Fabrik KG Hugenottenstraße 105 61381 Friedrichsdorf Germany Zhdankin, J. Org. Peracetic acid is a highly biocidal oxidizer that maintains its efficacy in the presence of organic soil. Peracetic acid is used at concentrations of 150–200 ppm on various food-contact surfaces. Similarly, Pedersen et al., [20] have used DPD colorimetric assay to measure peracetic acid and H2O2 separately using di erent reaction conditions and combining peroxidase enzyme. Efficient oxidative α-halogenation of 1,3-dicarbonyl compounds has been achieved Peracetic acid is sometimes used at a concentration of 4%, but there is no evidence from actual gnotobiotic applications that this is more effective than 1% (R. Orcutt, personal communication, March 2014). However, achieving a high level of asymmetric induction using its chiral variants is still a hard task and the catalytic asymmetric reaction is more difficult. Introduction. The effect of peracetic acid reprocessing on β2-microglobulin clearances has been carefully studied in the HEMO Study because middle-molecule removal was one of the primary interventions during that trial. Peracetic acid production and usage as a disinfectant may result in its release through various waste streams or directly into the environment. Am. The protein accumulation also decreases the water or hydraulic permeability of the dialyzer membrane but has little impact on small-solute clearances, suggesting that the adsorbed proteins foul or clog the pore structure but do not make the dialyzer membrane appreciably thicker. As a peroxide, it has the potential to detonate in response to shock or heat so handle with care. Peracetic acid is used at concentrations of 150–200 ppm on various food-contact surfaces. It is mostly found to be unstable, and easily decomposable (when in contact with oxygen, acetic acid, and other degradation products including hydrogen peroxide and water). Chem., 2012, Peracetic acid removes surface contaminants (primarily protein) on endoscopic tubing. Preparation ofPreparation of Peracetic Acid Continuously feeding CH 3 COOH and H 2 O 2 into an aqueous reaction medium containing a H 2 SO 4 catalyst. Peracetic acid [or peroxyacetic acid, CH 3 C(O)OOH, PAA] is an oxidant that is attracting greater interest in research and applications.1−10 The applications of PAA have occurred in variousindustries,includingfoodprocessing,medical,chemical, and pulp and paper industries, for its high oxidation capability Chem. For example, the decrease in clearances of β2-microglobulin observed in the HEMO Study was approximately 50% after four reuses for dialyzers containing high-flux cellulose triacetate membranes but insignificant for those containing polysulfone membranes. An alternative high-level disinfectant available in the United Kingdom contains 0.35% peracetic acid. During the epoxidation of alkenes, an oxygen atom is transferred from the peracid to the C=C double bond thus forming an oxirane ring. broad range of substrates encompassing conjugated and nonconjugated olefins. Soc., 2003, Monitoring and use data indicate that the general population may be exposed to peracetic acid via ingestion of food and through dermal contact with products treated with peracetic acid. Users should be aware that results of standardized testing methods can vary considerably. 2016, 18, 2528-2531. Several commercial formulations are available. $$\ce{CH3COOH + H2O2 <=> CH3COOOH + H2O}$$ PAA has proven to be an excellent sanitizer and disinfectant in the food, beverage, cosmetic, pharmaceutical, and agriculture industries for industrial water treatment, as well as an excellent disinfectant for use in the wastewater treatment industry. A contact time of at least 30 min is recommended. oxidant. The vapor generated when a 1–2% solution is sprayed at room temperature will inactivate the most resistant bacteria and mold spores within 15 min, and direct application of the liquid achieves the same action within 1 min (Trexler, 1984). Peracetic Acid. The new procedure allows the Old Chemist. Peracetic acid is composed of an equilibrium of acetic acid, hydrogen peroxide and water. Peracetic acid is produced by a reaction between hydrogen peroxide and acetic acid: Peracetic acid generated by perhydrolysis of N-acetylcaprolactam by hydrogen peroxide in alkaline conditions Biocidal active substances Peracetic acid generated from 1,3-diacetyloxypropan-2-yl acetate and hydrogen peroxide Peracetic acid Peracetic acid (C 2 H 4 O 3) is a mixture of acetic acid (CH 3 COOH) and hydrogen peroxide (H 2 O 2) in a watery solution.It is a bright, colorless liquid that has a piercing odor and a low pH value (2,8). Peracetic acid (CAS No. Steriplex™ SD has begun to be adopted for gnotobiotic use (C. Bell, personal communication, January 2014). However, it is stated by the manufacturer to be sporicidal, bactericidal, fungicidal, and viricidal; to rapidly inactivate Clostridium difficile and Bacillus subtilis spores; to be nonirritating; and to have a shelf life of 60 days after activation (Robison, 2012; sBioMed, 2013a, b, c). Y.-B. The resultant effect of protein adsorption, therefore, is a decrease in the removal of middle molecules. Such products can corrode stainless steel. Peracetic acid is believed to function in a similar fashion as other oxidizing agents by reacting with cellular proteins and enzymes. 71, 9912-9914. Liquid chlorine dioxide sterilants include Exspor™ (Ecolab Inc.) and Clidox-S™ (Pharmacal Research Laboratories). Google has not performed a legal analysis and makes no representation as to the accuracy of the status listed.) is a very efficient and practical catalyst for the epoxidation of a wide After processing, the devices should be used immediately or stored in a manner similar to that of a high-level disinfected endoscope.156-158 The sterilant, 35% peracetic acid, is diluted to 0.2% with tap water that has been filtered and exposed to ultraviolet light. As a sterilant, it is active against Gram-negative and positive bacteria, fungi and yeasts, but also against viruses and organic matter (Block 2001). Peracetic Acid (PAA) is an organic peroxide compound with the formula CH₃CO₃H. Moreover, results of standardized tests do not necessarily indicate effectiveness in the environment in which sterilants and procedures will actually be used (Gibson et al., 1995; R. Orcutt, personal communication, March 2014). Efficient oxidative α-halogenation of 1,3-dicarbonyl compounds has been achieved by employing a system comprising of sub-stoichiometric amounts of TiX 4 (X = Cl, Br) in the presence of environmentally benign hydrogen peroxide (H 2 O 2) or peracetic acid (MeCO 3 H) as the oxidants.
