摘要:
The invention concerns novel saccharic acid derivatives of general formula (I): MO2C-CHOR1-CHOR2-CHOR3-(CHOR4)n-R5, in which M is a hydrogen atom or an alkali metal or alkaline earth metal atom, R1, R2, R3, R4 and R6, independently of one another, represent a hydrogen atom or a group of formula (II), in which M has the above meaning, n is 0 or 1, R5 is a hydrogen atom, a CH2OR6-, CHO- or COOM- group, the compound on average having to contain two succinyl groups. The derivatives can be used, alone or in combination with other builders, in detergents or cleaning agents, have good biodegradability and can be obtained by the addition of maleic acid anhydride to saccharic acids. These builders can replace (co)polymer carboxylates in detergents or cleaning agents. The invention further concerns a phosphate-free detergent containing the builders according to the invention.
