Usage

General Description

Octaneperoxoyic acid, also known as peracetic acid or PAA, is a highly reactive organic peroxide compound with the chemical formula CH3CO3H. It is a colorless liquid with a pungent odor and is commonly used as a disinfectant and sanitizer in various industries, including food and beverage, healthcare, and agricultural sectors. PAA is effective against a wide range of microorganisms, including bacteria, fungi, and viruses, and is also used as a bleaching agent and a chemical intermediate in the production of other organic compounds. However, it is important to handle and use this chemical with caution due to its strong oxidizing and corrosive properties. Consequently, it is often diluted before use and requires careful handling and storage to prevent accidents and ensure safety.

Optimization of chemo-enzymatic epoxidation of cyclohexene mediated by lipases

This work describes the lipase-mediated epoxidation of cyclohexene. Lipases were used to generate peroxyoctanoic acid directly from octanoic acid and hydrogen peroxide and applied in situ to obtain cyclohexene oxide. Various parameters, which could affect this reaction, were studied such as lipases from different sources, organic solvents, temperature and acyl donor concentrations. Highest conversions to cyclohexene epoxide were achieved using a two-phase system of toluene or xylene/water with ROL (Amano F-Ap15 free Rhizopus orizae lipase) (84 and 80%) or CALB (Novozymes 435-immobilized Candida antarctica lipase type B) (>9 and 84%) as biocatalysts. Using PSL (Amano PS-free Pseudomonas sp) the conversions were in the range of 12-53%, but an improvement was obtained by the use of the ionic liquid 1-butyl-3-methylimidazolium tetrafluoroborate (20 to 41% in water/methyl dichloride).

Perdecanoic acid as a safe and stable medium-chain peracid for Baeyer-Villiger oxidation of cyclic ketones to lactones

Stability studies dedicated to high-energy compounds for a series of linear peracids (C6-C12), including sensitivity to mechanical impulse (shock and friction), as well as electrical (spark) and thermal sensitivity (temperature and heat of decomposition), were presented in this work for the first time. Studies revealed that all peracids were insensitive to shock, while in the case of the other sensitivity tests sharp differences between results for C8 and C10 peracids were observed. Taking into account the relatively high initial temperature of decomposition (above 64 °C) perdecanoic acid was selected as a safe alternative to commonly used hazardous short-chain peracids. Next, a new method for the Baeyer-Villiger oxidation was presented. Oxidation of 2-adamantanone was chosen as a model reaction. Peroctanoic, perdecanoic and perdodecanoic acids were tested as oxidants. Peroctanoic acid was the most reactive but taking into account both safety and kinetic issues, perdecanoic acid was selected for the further studies. The influence of reaction conditions on reaction rate was investigated. Optimized reaction conditions were suggested (two-fold molar excess of peracid with respect to the ketone, toluene as a solvent, 35 °C). This exploratory study offers promise with regard to the development of safer alternatives to peracetic acid in industrial oxidation.
