Manufacturing Process
200 grams of allyl acetate, 450 grams of glacial acetic acid and 3.71 grams of cobaltous bromide were charged to the reactor and the mixture was heated to 100°C.
Pure oxygen was then introduced into the reactor below the surface of the liquid reaction mixture at the rate of 0.5 standard cubic feet per hour.
Initially, all of the oxygen was consumed, but after a period of time oxygen introduced into the mixture passed through unchanged.
During the course of the reaction, a small quantity of gaseous hydrogen bromide (a total of 1.9 grams) was introduced into the reaction zone, along with the oxygen.
The reaction was allowed to continue for 6 hours following which the reaction mixture was distilled.
Essentially complete conversion of the allyl acetate took place.
A yield of 116 grams of glycerol triacetate was obtained, this being accomplished by distilling the E1518 Glycerine triacetate overhead from the reaction mixture, at an absolute pressure of approximately 13 mm of mercury.
