    Abstract: The invention relates to a method for producing a peroxyacetic acid or peroxypropionic acid solution by reacting acetic acid or propionic acid with hydrogen peroxide in the presence of a polyphosphoric acid catalyst. The catalyst used in the inventive method is a water-free solution that is obtained by dissolving 0.1 to 99 % by weight, especially 1 to 35 % by weight (based on the solution) of a polyphosphoric acid in the carboxylic acid that is to be converted to the peroxycarboxylic acid. The catalyst solution is preferably produced using molten polyphosphoric acid on the site of production of the same.

    Abstract: A process for producing hydroperoxides by oxidizing a hydrocarbon with an oxygen-containing gas in the presence of a specified compound to selectively convert the hydrocarbon into a corresponding hydroperoxide. The specified compounds are those capable of trapping free radicals, and preferred examples thereof include oxygen, nitrogen, phosphorus, sulfur, carbon and silicon radicals, and compounds capable of forming such radicals in a reaction system. This process is applicable to the oxidation of hydrocarbons including arylalkylhydrocarbons such as cumene, cymene, m-diisopropylbenzene, p-diisopropylbenzene, 1,3,5-triisopropylbenzene, isopropylnaphthalene, diisopropylnaphthalene, isopropylbiphenyl and diisopropylbiphenyl.

    Abstract: Evaporation of water from an aqueous dispersion of a solid peroxide such as benzoyl peroxide is retarded by the incorporation of carboxylic acid salt. The carboxylic acid salt renders the aqueous dispersion less susceptible to explosive decomposition when exposed to external triggering events such as impact, heat, friction or contamination, yet does not interfere with the ability to achieve and maintain a stable, small particle size dispersion having desirable viscosity and flow properties.
