Production
E1518 Glyceryl Triacetate can be derived from the esterification of glycerol and acetic acid.
After preheating glycerol to 50-60 ° C, add acetic acid, benzene and sulfuric acid.
Heat and stir for refluxing dehydration, and recycle the benzene.
Then add acetic anhydride for heating of 4h.
After cooling, the mixture was neutralized with 5% sodium carbonate to pH 7, and the crude layer was dried and the crude oil was dried with calcium chloride.
Distill under reduced pressure, collect the 128-131 ° C (0.93 kPa) fraction, namely E1518 Glyceryl Triacetate.
