摘要
综述了固体超强酸TiO2 /SO4 2 -,磷钨、硅钨杂多酸及固载杂多酸盐TiSiW12 O4 0 /TiO2 ,浓硫酸 (微波常压法 ) ,Lewis酸 (FeCl3·6H2 O ,Fe2 (SO4 ) 3·xH2 O)等几种不同催化剂催化合成对羟基苯甲酸酯的实验结果。分析各种固体催化剂对该酯化反应的催化活性、选择性。
In this paper,the catalytic of p-hydroxybenzoic esters,super solid acid TiO 2/SO 4 2- ,heteropolyacid of phosphor and silicon,TiSiW 12 O 40 /TiO 2,concentrated H 2SO 4 undermierowave irradiation and normal pressure,Lewis acid(FeCl 3·6H 2O,Fe 2(SO 4) 3·xH 2O)as catalyst was introduced.The result was showed that the catalytic activity selectivity and regeneration in the reaction of synthesizing esters.
