Title: The Synthesis of Diethyl Sebacate Catalyzed by SO_4~(2-)-TiO_2-La~(3+)Rare earth Solid Superacid
Abstract: The synthesis of diethyl sebacate from absolute ethanol and sebacic acid with rare earth solid superacid SO 2- 4 TiO 2 La 3+ as catalyst has been studied. The influence factors of the reaction were investigated. The results showed that the optimum conditions are as follows. The weight of the catalyst was 1 0 g (if the weight of sebacic acid was 0 1 mol); molar ratio of absolute ethanol to sebacic acid was 4 0∶1; the reaction time was 3 0 h; the taking water reagent (benzene) was 15 mL. The yield of diethyl sebacate was about 96 8%.
