ABSTRACT:
The invention relates to salts of alkyl esters of carboxyethyl(alkyl)phosphinic acid, where the salts have the formula (I)in-line-formulae description="In-line Formulae" end="lead"?R1—P(═O)(OX)—CH2—CH2—CO2R2in-line-formulae description="In-line Formulae" end="tail"?in which R1and R2are identical or different and, independently of one another, areC1-C20-alkyl, C2-C20-alkenyl, C1-C20-alkynyl, and/or C6-C20-aralkyl, andX is an alkali metal, an element of the second main and transition group, an element of the third main and transition group, an element of the fourth main and transition group, an element of the fifth main and transition group, an element of the sixth main group, an element of the seventh transition group, or an element of the eighth transition group, and also to processes for their preparation, and to their use.
