Title (EN) PROCESS FOR MAKING ESTERS OF 2-ACETOXYALKANOIC ACIDS USING AN ALPHA-HYDROXYALKANOIC ACID ESTER AND AN ACETATE ESTER AS STARTING MATERIALS
(FR) PROCÉDÉ DE PRODUCTION D'ESTERS D'ACIDES 2-ACÉTOXYALCANOÏQUES UTILISANT UN ESTER D'ACIDE ALPHA-HYDROXYALCANOÏQUE ET UN ESTER D'ACÉTATE EN TANT QUE MATÉRIAUX DE DÉPART
Abstract: front page image
(EN)2-Acetoxyalkanoic acid esters are made in a reaction of an α-hydroxyalkanoic acid ester and an acetate ester in the presence of a transesterification catalyst. Unlike previous methods for making 2-acetoxyalkanoic acid esters, this process proceeds in high yield and high selectivity to the desired product.
(FR)Des esters d'acide 2-acétoxyalcanoïque sont obtenus à l'issue de la réaction d'un ester d'acide alpha-hydroxyalcanoïque et d'un ester d'acétate en présence d'un catalyseur de transestérification. Contrairement aux précédents procédés de production d'esters d'acide 2-acétoxyalcanoïque, ce procédé présente un rendement élevé en produit recherché et une grande sélectivité.
