| titleOfInvention | Method for producing alpha-hydroxycarboxylic ester |
| abstract | This invention provides a more efficient process for alpha-hydroxycarboxylic ester production, in which the alpha-hydroxycarboxylic ester is more effectively inhibited or prevented from undergoing side reactions than in conventional techniques. The process for producing an alpha-hydroxycarboxylic ester comprises the following steps (1) to (3): a step (1) in which either (i) a 1,2-diol and the same or another 1,2-diol or (ii) a 1,2-diol and an alcohol are reacted in the presence of oxygen to obtain a reaction product containing an alpha-hydroxycarboxylic ester; a step (2) in which the reaction product obtained in the step (1) is distilled under vacuum to separate out the alpha-hydroxycarboxylic ester; and a step (3) in which part or all of the water is removed from the reaction product obtained in the step (1) and a mixture comprising the 1,2-diol and/or alcohol remaining unreacted is supplied to the step (1). |
