Abstract (en)
[origin: CA2845666A1] The invention relates to a continuous method for producing alpha-hydroxycarboxylic acid esters, at least one alpha-hydroxycarboxylic acid amide, which is present in the liquid phase, being reacted with an alcohol in the presence of a catalyst. The method is characterized in that the obtained alpha-hydroxycarboxylic acid esters are at least partially removed from the reaction mixture by means of the gas phase.
