Abstract: The invention relates to a raw ester of an esterification reaction catalyzed by a metal-containing esterification catalyst regenerated by a) mixing the raw ester at a temperature T of more than 100°C under a pressure p that is equal to or greater than the vapor pressure of water at the temperature T with an aqueous base, b) relaxing the ester-base mixture and evaporating water, c) mixing the obtained fluid phase with water forming a water-in-oil emulsion, d) distilling water out of said emulsion and e) filtering the ester. Said method results in esters having low acid value and residues accrue in easily filterable form in the solid catalyst residues.

Abstract: Procedimiento para la elaboración de un éster crudo de una reacción de esterificado, que es catalizada con uncatalizador de esterificado que contiene metal, en el que a) el éster crudo se mezcla con una base acuosa a una temperatura T de más de 100ºC bajo una presión p,que es igual o mayor que la presión de vapor de agua a la temperatura T, b) la mezcla de éster-base se descomprime y el agua se evapora, c) la fase líquida obtenida se mezcla con agua bajo formación de una emulsión de agua en aceite, d) a partir de la emulsión se separa agua por destilación, y e) se filtra el éster

Abstract: A process is described for preparing esters of an acid component selected from among polybasic C 4 -C 10 carboxylic acids and an alcohol component selected from among C 3 -C 12 alkanols or from among C 3 -C 12 alkanediols, the alkyl chain of which may have interruption by from 1 to 3 oxygen atoms, by a) heating at boiling point, in a reaction zone and in the presence of an esterification catalyst, a mixture essentially consisting of the acid component or of an anhydride thereof and of the alcohol component, b) using rectification to separate the vapor comprising alcohol and water into an alcohol-rich fraction and a water-rich fraction, and c) returning the alcohol-rich fraction into the reaction zone and conducting the water-rich fraction out of the process. The process is simple to carry out and permits rapid achievement of essentially quantitative conversion.
