本文以宁明膨润土为原料，制备出钛交联膨润土，研究了钛交联膨润土在醋酸正丁酯合成反应中的酯化催化性能．实验结果表明，钛交联膨润土具有比较优良的酯化催化性能，在相同条件下，其酯化催化性能优于传统催化剂硫酸．

英文摘要：

Based on the purification and modification of bentonite, titanium-cross-linked Bentonite was prepared with Ning-ming Dentonite as raw material, and the catalytic capability of titanium-cross-linked Bemtpmote in synthesis of n-butyl acetate was also studied. The experiment result shows that titanium-cross-linked Bentonite have the better catalytic capability in the reaction of esterification than that of sulfuric acid at the same conditions.
