漂白活化剂制备的研究

Study of preparation of bleach activators

介绍了近10年来漂白活化剂制备的进展。漂白活化剂是含有氧或氮酰基团的化合物,可与强亲核过氧酸反应产生过乙酸,从而提高漂白效果。它广泛用于织物、硬质表面和餐具的洗涤。介绍了漂白活化剂烷酰氧苯甲酸可由对(间)羟基苯甲酸与各类酰化剂(从脂肪酸、酰氯、酸酐中选取)反应制备。此外,还介绍了胺类、糖类等化合物与酰化剂反应合成漂白活化剂。

The recent development of bleach activators were described.Bleaching acitvators are compounds with O or N bound acetyl groups,which are able to react with strong nucleophilic hydroperoxy atom to yield peroxyacetic acid.They provide enhanced bleaching effects.They are useful for washing fabrics,hard surfaces and tableware.Bleaching activator acyloxybenzoic acids can be produced by treating p-hydroxybenzoic acid with acylationg agents which can be chosen from fatty acids,acyl chlorides of fatty acids and acid anhydrides.Besides,amine and carbohydrate compounds are also can be acylated to prepare bleach activator.
