Abstract
PURPOSE: In the esterification of an organic carboxylic acid and an alcohol in the presence of an azeotropic agent while formed water being taken out from the system, to reduce the amount of alcohol used and it loss, and to raise productivity and economical advantages, by adding the alcohol dividedly.
CONSTITUTION: An organic acid (e.g., acetic acid, monochloroacetic acid, etc.) is reacted with an alcohol (e.g., methanol, etc.) in the presence of an azeotropic agent (e.g., cyclohexane, etc.) while formed water being taken out from the system, to given an organic carboxylic ester. In the reaction, 1.0W2.0 times, preferably 1.1W1.4 times the theoretical amount of alcohol is dividedly added to the organic carboxylic acid. In methyl esterification having many problems in conventional method, the esterification is carried out almost quantitatively to give a methyl ester in high yield.
