Abstract

A method of preparing an aliphatic peracid comprises oxidizing with hydrogen peroxide an aliphatic carboxylic acid in the presence of a nuclear sulphonated aromatic hydrocarbon cation-exchange resin in its hydrogen form. Suitable resins are sulphonated polymers of polyvinyl aryl compounds, such as divinyl benzene and the sulphonated copolymers of such polyvinyl aryl compounds with monovinyl aryl compounds such as styrene described in Specification 571,029, [Group IV]. Preferred are aliphatic acids of 1 to 4 carbon atoms. When a liquid, the acid is usually employed in excess as the reaction medium. Reaction temperatures of 15 DEG to 70 DEG C., preferably 25 DEG to 50 DEG C. are suitable. The hydrogen peroxide is of at least 25 per cent and is preferably of 35 per cent strength. In Examples (1) and (2), glacial acetic acid is oxidized to peracetic acid by treatment with 50 per cent aqueous hydrogen peroxide at 40-45 DEG C. in the presence of a cation exchange resin (in the hydrogen form) obtained by sulphonating a copolymer of styrene and about 8 per cent divinyl benzene, the resin containing about one -SO3H group per benzene ring; (3) perpropionic acid is similarly prepared from propionic acid.
