Process for making esters of 2-acetoxyalkanoic acids using an ?-hydroxyalkanoic acid ester and an acetate ester as starting materials

Patent number: 10294188

Abstract: 2-Acetoxyalkanoic acid esters are made in a reaction of an ?-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.

Type: Grant
