Title (EN) DIACYLATED DIPERCARBOXYLIC ACID AS BLEACHING AGENT
(FR) ACIDES DIPERCARBOXYLIQUES DIACYLES
Abstract:
(EN) The invention concerns diacylated dipercarboxylic acids according to general formula (I), in which R1 and R2 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, R1 and R2 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 R1 and R2 are acetyl or both of R1 and R2 are nonyl. The invention also concerns a method of their preparation, a composition useful for bleaching and a method of bleaching.
(FR) L'invention concerne des acides dipercarboxyliques diacyles de formule générale suivante (I) dans laquelle R1 et R2 sont des groupes hydrocarbures composés de 1 à 15 atomes de carbone, et X attire les électrons en étant un groupe phényle optionnellement substitué, un hétérocycle optionnellement substitué dans lequel l'hétéroatome est positionné de façon que de 2 à 4 atomes de carbone soient présents entre l'hétéroatome et chacun des carbones carbonyles du diperacide, ou en comprenant au moins un groupe fonctionnel attirant les électrons positionné de façon qu'une chaîne carbone ayant de 2 à 4 atomes de carbone soit présente entre le groupe attirant les électrons et chacun des carbones carbonyles du diperacide, le groupe attirant les électrons contenant de l'oxygène, du soufre, de l'azote, du phosphore, de l'halogène, du phényle optionnellement substitué ou au moins deux liaisons doubles conjuguées, et R1 et R2 étant des groupes hydrocarbures comportant de 1 à 15 atomes de carbone, exceptés les composés dans lesquels X est constitué d'un groupe phényle dont les carbones carbonyles sont en positions 1 et 4 et dans lesquels R1 et R2 sont tous deux soit des acétyles, soit des nonyles. L'invention concerne également un procédé de préparation, une composition pour blanchiment et un procédé de blanchiment.
