Min Zhang · Hecheng huaxue · 2001
Phosphyotungstic acid was used as the catalyst for preparation of glycerol triacetate. The optimum reaction conditions are as follows:mass ratio of catalyst to reactant 3.8%, reaction temperature(oil bath) 135℃~155℃, reaction time 7h. Under the optimum reaction conditions the yield was up to 84.6% and the catalyst was reusable.
