1318689 Glycerol di- and tri-acetates KNAPSACK AG 2 Nov 1971 [14 Nov 1970] 50882/71 Heading C2C Glycerol triacetate and glycerol diacetate are prepared by reacting a solution of allyl acetate in acetic acid containing between 1À5 and 15 wt. per cent of acetaldehyde with a mixture of molecular oxygen and inert gas, (e.g. N 2 , carbon oxides), at 30-250‹ C. and 1-200 ats. absolute in the absence of catalysts. The acetic acid solution preferably contains 0À1-1À0 moles of acetaldehyde per mole of allyl acetate. The glycerol acetates may be hydrolysed by conventional methods to yield pure glycerol and the reaction may be carried out continuously.
