Abstract

Procedure for the esterifying extraction of mercaptocarboxylic acids from aqueous solutions, characterized in that a polar organic solvent is used as the absorbent in the mixture with the stoichiometric part or a reduced excess of the desired alcohol for the transformation, where the esterification is verified during the extraction and during the subsequent distillation of the unconverted part of the absorbent -which consists of solvent and excess alcohol- and of the reaction water, and the distillate after adding the used alcohol is used again for the extraction.
