Abstract: A process for the separation of acids from reaction mixtures by means of an auxiliary base (I) is characterized by (a) the base (I) forming a salt with the acid that is liquid at temperatures that do not lead to significant decomposition of the product during separation of the liquid salt (b) the salt of the base (I) forming two non-miscible phases with the product or solution of the product in a suitable solvent.
