| Abstract: | In the presence of solid superacid catalyst SO 4 2- /Fe 2O 3 TiO 2, The glycerol triacetate was synthesized from glacial acetic acid and glycerol. The optimum conditions are as follow:mole ratio of glycerol to glacial acetic acid is 1∶4.0, reaction time of reflux 4h, mass of catalyst 8% of glycerol. The yield of glycerol triacetate reaches 96%. The catalyst have many advantages, such as easy to be recovered, feasible to be used repeatedly, and less pollution to the environment. |
