Catalytic Synthesis of Glycerol Triacetate with the Solid Ultra Strong Acid SO_4~(2-)/Sb_2O_3/SiO_2 Catalysts

Wensheng Wu

Abstract

Glycerol triacetate was synthesized from glacial acetic acid and glycerol catalyzed by the new solid ultra strong acid SO42-/Sb2O3/SiO2 made by myself.The best synthesis condition of glycerol triacetate was investigated.The experiment results showed that the optimum reaction conditions were as follows:when the molar ratio of glacial acetic acid to glycerol was 1.0:2.0,the dosage of SO42-/Sb2O3/SiO2 was 2.0% and reactive time was 4 hour.The esterification yield reached to 98%.The product was characterized by refractive index and IR.
