| Abstract: | Glycerol triacetate was synthesized from glacial acetic acid and glycerol catalyzed by the new solid ultra strong acid SO4^2-/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 SO4^2-/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. |
