Abstract
The present invention provide a production process for a hydroxyalkyl ester which comprises the step of carrying out a reaction between a carboxylic acid and an alkylene oxide in the presence of a catalyst, wherein the production process sufficiently enhances the conversion or selectivity in the reaction. The production process is characterized in that the reaction is carried out in a reaction liquid under conditions where a relationship a<b is kept throughout the reaction wherein “a” is a molar concentration (mol %) of the carboxylic acid in the reaction liquid and wherein “b” is a molar concentration (mol %) of the alkylene oxide in the reaction liquid.
