摘　　要： 选用超强酸树脂ＤＯＯ１－ＡｌＣＩ＿３代替强酸性阳离子交换树脂及浓硫酸作催化剂，对乳酸正了酯合成反应进行了探索性研究，讨论了影响产率的多种因素，最佳条件下酯化反应时间缩短，乳酸正丁酯产率可达到９９．５％。对其他酯类物质也进行了合成试验，获得了满意的结果。 Abstract In this method superacid resin as catalyst,instead of the strong acid cation exchange resinand sulfuric acid was used to synthesis n- butyllactate. Some factors of affection reaction werediscussed.Under optimum conditions,the esteri-fication time was shorten very much ,and the to-tal yield was 99.5%. In the other hand,su-peracid resin as catalyst was used to synthesisother esters,the results of the experiment weresatisfactory.
