    摘要: A process for preparing siloxy carboxylates is characterized by reaction of C2-C10-monocarboxylic acids with halosiloxanes of the general formula (I), Hal-(SiR2—O)x—SiR3  (I) in which Hal is the same or different and is fluorine, chlorine, bromine or iodine, R is hydrogen, C1-C10-alkyl or C6-C14-aryl and x is an integer from 1 to 20, to form hydrogen halide in the presence of an auxiliary base, in which the auxiliary base forms, with the hydrogen halide, a salt which forms two immiscible phases with the siloxy carboxylate or the solution of the siloxy carboxylate in a suitable solvent and is removed by a liquid-liquid separation. The process enables simple and economically viable preparation of siloxy carboxylates.
