Abstract:

The rare earth solid superacid SO 2- 4/TiO 2/La 3+ was prepared. The synthesis of diethyl sebacate has been studied using ethanol absolute and sebacic acid as reactants, and rare earth solid superacid SO 2- 4/TiO 2/La 3+ as catalyst. The influence factors of reaction were investigated. The results show that it is a good catalyst for esterifications.
