Salts of alkyl- and/or alkenylsuccinic acid half-amides The invention relates to salts of alkyl- and alkenyl- succinic acid half-amides of the formulae Image and/or Image ( Ia) ( Ib) in which R1 is C6-C100-alkyl or C6-C100-alkenyl (straight-chain or branched), R2 is a deoxysaccharide radical which is derived from mono-, di- or oligosaccharides, R3 is hydrogen, C1-C6-alkyl or R2, and X+ is a proton, an alkali metal ion, the equivalent of an alkaline earth metal ion, or an ammonium ion of the formula N+HR4R5R6 (II) or of the formula N+HR2R3R4 (III), in which R4, R5 and R6 independently of one another are hydrogen, C1-C20-alkyl, a hydroxyl group, C1-C6- hydroxyalkyl or C3-C6-polyhydroxyalkyl and R2, R3 and R4 have the abovementioned meanings. The invention furthermore relates to a process for the preparation of the salts of alkyl- and/or alkenylsuccinic acid half-amides, which comprises reacting an alkyl- and/or alkenylsuccinic acid anhydride with carbohydrates containing amino groups in the presence of basic com- pounds.
