| 摘 要： | SnCl4是路易斯酸，对一些酸催化反应有较好的催化效果。但在均相反应体系中，催化剂难以分离，不能重复使用。SnCl4在空气中易强烈水解，且腐蚀性较强也限制了其实际应用。本文在乙醇介质中通过蒸发法制得SnCl4／HMST-5A复合物催化剂。并用差热分析、红外光谱和紫外光谱对催化剂进行了表征，考察其酯化反应中的催化性能，表明sSnCl4／HMST-5A活性高，重复使用性能好。

| Abstract: | HMST-5A/SnCl_4 complex catalyst is prepared by using MST-5A and SnCl_4 in alcohol solution as a medium,and characterized by DTA,IR and UV-vis spectrum.The preparation method is simple and the catalyst is easily separated.The experimental results show that the catalyst has high activity on the esterification of n-butyl alcohol and acetic acid and can be used repeatedly. |
