摘要
多元脂肪酸酯,是聚合物的优良助剂。本文主要介绍以烃基酸性硫酸酯类为催化剂,合成多元脂肪酸酯的工艺过程。这种合成方法,可使多元酸(或醇)的酯化率达到95％～98％。
Polybasic aliphatic ester is well-known as a good assistant to polymericmaterial. This paper mainly explores the synthetic process of the polybasicaliphatic ester with the hydrocarbyl acid sulfate as catalyst. It concludesthat the esterificution rate of the polybasic acid (or alcohol) can reach upto the range from 95 to 98 percent if the above method is used.
