磺化聚氯乙烯催化合成乳酸正丁酯

Catalytic Synthesis of n-Butyl Lactate by Sulfo-Polyvinyl Chloride Resin

将磺化聚氯乙烯催化剂应用于乳酸正丁酯的合成中，由乳酸和正丁醇反应生成乳酸正了酯．当0．1摩尔乳酸，0．4摩尔正丁醇和1．0克催化剂回流反应2小时，产品收率达85．6％．同时研究了催化剂的重复使用情况．

In the paper, the catalyst of sulfo - polyvinyl chloride was used in the synthesis of n - butyl lactate. n-Butyl alcohol reacted with lactic acid in the presence of sulfo-polyvinyl chloride to yield n-butyl lactate. Thus a mixture of 0. 1mol. lctic acid, 0.4mol. n - butyl alcohol and 1.0g catalyst were heated for 2.0 hours at refluxing temperature, the yield was 85.6%. The reusabity of the catalyst was studied.
