摘要:本文研究Ti2SnC催化无水乙醇和冰乙酸合成乙酸乙酯的催化活性。考察催化剂用量、原料配比、反应时间等因素对酯化率的影响。经实验得最佳实验条件：催化剂用量0.2000g，醇酸摩尔比为1：3.6，反应30min，可使酯化率达到88.12%。

　　　依次做催化剂回收1次、2次、3次、4次时的酯化率，随着催化剂重复使用的次数增多酯化率依次减小。

　　　通过大量的资料查询，最后选了乙酸乙酯这个体系来研究，主要是因为此反应体系对于其他酯化反应体系来说是最简单的，而且通过实验研究后酯化率能达到80%以上，所以也达到我们的实验要求。

　　　在灼烧相同的时间下，催化剂灼烧温度越高，酯化率越高；在灼烧温度相同的条件下，催化剂灼烧的时间越长，酯化率越高。

ABSTRACT:This Paper studied the synthesis of acetate ester with absolute alcohol and acetic acid as reactant，with titanium sulfate as catalyst. After investigating catalyst amount，reactant ration and reaction time，the betterreaction fact0rs had been found： the acetic acids is 0.2000g，the mole ration of alcohol andacid is1:3.6,the reaetion time is 30 rain，the recovery rate of EtOAc is over88.12%.Compared with 98 H2SO4% ,the result was better when titanium sulfate is used as catalyst．

　　Ordinal test the rate of esterification by catalysts recycling 1 times, 2 times, 3 times, 4 times, we found that as increasing the number of repeated use of catalysts desertification rate in turn decrease. 

　　　Through a lot of material queried, we finally chose this ethyl acetate system to study, mainly because compared with other esterification reaction system, this reaction system is the most simple and this experiments can achieve the esterification rate more than 80%, and this condition also achieve our experimental requirements. 

　　　At the same burning time, catalyst burning hotter, esterification rate higher; In calcinations temperature under the same conditions, the more of catalyst burning time , the higher of esterification rate.
