Abstract
PURPOSE: To form the titled partial ester useful as a modifying agent or a crosslinking agent for various resins in high selectivity, by subjecting a lower alkyl ester of a mercaptocarboxylic acid to the ester interchange reaction with a polyhydric alcohol.
CONSTITUTION: (A) one or more polyhydric alcohols, e.g. pentaerythritol, having 2W6 hydroxyl groups in the molecule is reacted with (B) one or more lower alkyl esters of mercaptocarboxylic acids, e.g. ethyl 2-mercaptoacetate expressed by the formula HS-R1-CO2R2 (R1 is 1W2C methylene; R2 is 1W4C alkyl), preferably in the presence of 0.001W10wt%, based on the charged amount of the raw materials (A) and (B), p-toluenesulfonic acid, at 50W160°C to give the aimed partial ester, e.g. pentaerythritol tris-(2-mercaptoacetate).
