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. The SO_4 ~ (2 -) / TiO_2 and SO_4 ~ (2 -) / ZrO_2 solid superacid were synthesized and used as catalysts for the synthesis of diamyl maleate. Meanwhile, the catalytic effect with sulfuric acid and p - toluenesulfonic acid Made a comparison. When the solid superacid catalyst is used, the catalyst is separated from the product easily and the product post-treatment is simple, thereby simplifying the process, saving the raw materials and energy, reducing the waste water, and being superior to the traditional sulfuric acid and the p-toluenesulfonic acid catalyst.
