聚氯乙烯与氯磺酸反应合成了一种高分子催化剂,研究了它对羧酸和醇的酯化反应的催化活性,探讨了催化合成乙酸正丁酯的反应条件,并催化合成了乙酸、丙酸和丁酸的十一种酯,收率为82—92％。
Polyvinyl chloride was synthesized with chlorosulfonic acid to synthesize a kind of macromolecule catalyst. Its catalytic activity for esterification of carboxylic acid and alcohol was studied. The reaction conditions for the synthesis of n-butyl acetate were discussed, and the synthesis conditions of acetic acid, Eleven esters of propionic and butyric acids were obtained in 82-92% yield.
