摘　　要：首次将聚氯乙烯－ 三氯化铁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丁酯。当 ０．１ ｍ ｏｌ乳酸，０．４ ｍ ｏｌ正丁醇和 １．０ ｇ 催化剂回流加热 ２．０ ｈ，产品收率达 ９８．６％ 。In the paper,the catalyst of polyvinyl chloride-ferric chloride(PVC-FeCl 3) was used in the synthesis of n-butyl lactate.n-Butyl alcohol reacted with lactic acid in the presence of PVC-FeCl 3 to yield n-butyl lactate.Thus,a mixture of 0.1 mol lactic acid,0.4 mol n-butyl alcohol and 1.0 g catalyst were heated for 2.0 h at refluxing temperature,the yield was 98.6%.
