(1) In the esterification reaction of an organic acid or amino acid hydrochloride and an aminoalcohol hydrochloride, the reaction system in the presence of an organic solvent is heated to reflux while passing hydrogen chloride gas, and the generated water is continuously converted to hydrochloric acid. A method is known in which the esterification reaction proceeds while distilling off (Japanese Patent Publication No. 45-
14771 and 46-35246). In this method, the esterification reaction is carried out under normal pressure, and the reaction proceeds relatively smoothly in the initial stage of the reaction, but the reaction rate gradually decreases and the yield is low. (2) A method is known in which, when an amino acid hydrochloride and an aminoalcohol hydrochloride are heated for esterification, hydrogen chloride gas is absorbed in the reaction system in the absence of an organic solvent that forms an azeotropic mixture with water and the reaction is performed. It has been (Japanese Patent Publication Sho 59-45)
667). This method is a method that requires a high vacuum of 10 mmHg or less, though a complicated work of repeating reaction and dehydration 5 to 6 times is performed to obtain a yield of 75 to 80%. (3) When the esterification reaction of amino acid hydrochloride and aminoalcohol hydrochloride is carried out by heating under reflux while passing hydrogen chloride gas into a reaction system in the presence of an organic solvent, a surfactant is added to the reaction solution. A method of doing so is known (Japanese Patent Publication No. 60-7978).
