Production method: it is obtained by esterification of glycerol and acetic acid. After preheating glycerol to 50-60 ℃, add acetic acid; Benzene and sulfuric acid. Heat, stir, reflux and dehydrate, recover benzene after dehydration, add acetic anhydride and heat for 4H. After cooling, neutralize pH to 7 with 5% sodium carbonate, remove the water layer, and dry the crude oil with calcium chloride. Distillation under reduced pressure and collect 128-131 ℃ (0.93kpa) fraction, which is glycerol triacetate.
Uses: used as perfume fixative, solvent and toughening agent. For cosmetics; Production of medicine and dyes, plasticizer for cigarette filter rod, etc.
