A method for the production of alpha - hydroxycarboxylates

摘要

The present invention relates to a continuous process for preparing alpha - hydroxycarboxylic esters, wherein at least one alpha - hydroxy carboxylic acid amide, which is present in the liquid phase, with an alcohol is converted in the presence of a catalyst, which is characterized in that the resulting alpha - hydroxycarboxylic acid esters at least partially out of the reaction mixture is separated via the gas phase.
