复合固体超强酸催化合成醋酸正丁酯的研究

The Study of Composite Solid Superacid Catalytic Synthesizing Butyl Acetate

研究了以复合型固体超强酸为催化剂催化合成醋酸正丁酯，探讨了酯化反应条件和催化剂的制作工艺对酯产率的影响。实验结果表明，复合型固体超强酸（ＳＯ２－４ ／ＺｒＯ２－ Ａｌ２Ｏ３）具有较高的催化活性和选择性，在最佳工艺条件下酯产率可达９６％ ，产品质量符合国标要求。该工艺操作简便，条件易控制，对环境无污染。

This paper studies catalytic synthesis of butyl acetate,using composite solid superacid.It also discusses the condition of esterifical reaction and making technology of catalyst.As a result,Composite solid superacid (SO 2- 4/ZrO 2-Al 2O 3)has higher catalytic activity and selectivity.Under the best condition,the yield of ester can reach 96 percent and the quality keeps up with national standard.This technology is easily operated and the condition is easily controled.There is also no pollution.
