摘要
合成了 SO_4^(2-)/TiO_2、SO_4^(2-)/ZrO_2固体超强酸,并把它作为催化剂用于马来酸二戊酯的合成,同时与硫酸、对甲苯磺酸的催化效果作了比较。该固体超强酸作催化剂的情况下,催化剂与产品分离容易,产品后处理简单,从而简化了工艺,节约了原材料和能源,减少了废水,优于传统的硫酸、对甲苯磺酸催化剂.
Solid super acid catalysts,SO_4^(2-)/TiO_2,SO_4^(2-)/ZrO_2 are prepared and used insynthesizing dipentyl maleate.In comparison with sulfuric acid and p-toluenesulfonic acid,the solid super acid catalysts show many advantages:readiness inisolating the products from the catalyst,convenience in treating the products,decrease of waste water,reduction in power consumption,and being much moreeconomical.
