Title: (EN) Diacylated dipercarboxylic acid as bleaching agent
Abstract:
(EN)

##STR1## The invention concerns diacylated dipercarboxylic acids according to general formula (I), in which R.sub.1 and R.sub.2 are hydrocarbon groups having from 1 to 15 carbon atoms, and X is electron attracting by being an optionally substituted phenyl group, an optionally substituted heterocycle in which the hetero atom is positioned so that from 2 to 4 carbon atoms are present between the hetero atom and each one of the carbonyl carbons of the diperacid, or by comprising at least one electron attracting functional group positioned so that a carbon chain having from 2 to 4 carbon atoms is present between said electron attracting group and each one of the carbonyl carbons of the diperacid, wherein the electron attracting group contains oxygen, sulfur, nitrogen, phosphorus, halogen, optionally substituted phenyl, or at least two conjugated double bonds, R.sub.1 and R.sub.2 are hydrocarbon groups having from 1 to 15 carbon atoms, except compounds in which X consists of a phenyl group having the carbonyl carbons in 1,4 position and both of R.sub.1 and R.sub.2 are acetyl or both of R.sub.1 and R.sub.2 are nonyl. The invention also concerns a method of their preparation, a composition useful for bleaching and a method of bleaching.
