本文研究新型无机固体超强酸 SO_4~(2-)/TiO_2-ZrO_2的制备方法,并用它代替通用的硫酸、对甲苯磺酸作为合成马来酸二正丁酯的催化剂,取得了较理想的结果。
In this paper, the preparation of a new type of inorganic solid superacid SO_4 ~ (2 -) / TiO_2-ZrO_2 was studied, and it was used instead of the common sulfuric acid. The p-toluenesulfonic acid was used as the catalyst for the synthesis of di-n-butyl maleate. .
