SO42-/TiO2-Al2O3-SnO2固体超强酸的制备及其催化合成马来酸二正成酯
Preparation of SO42-/TiO2-Al2O3-SnO2 Type Solid Superacid and Its Catalytic Properties for the Synthesis of Dipentyl Maleate
【摘要】 制备了酸强度为-14.52的/TiO2-Al2O3-SnO2固体超强酸,考察了浸渍液H2SO4的浓度、金属原子配比、焙浇温度及焙浇时间对其酸强度的影响.用该催化剂催化合成马来酸二正戊酯,具有很好的催化性能.
【Abstract】 This paper prepares /TiO2-Al2O3-SnO2 solid super acid,and studies the effects of. atom ration of Ti: Al: Sn,calcination temperature, calcination time and concentration of H2SO4 solutions, on the acid strength. /TiO2-Al2O3-SnO2 catalysts have high activity for the synthesis of Dipentyl maleate.
