Preparation of ethylene glycol diacetate
1-liter, short-necked, round bottom flask, fitted with a reflux condenser is charged with a mixture of 60 g ethylene dibromide, 20 g glacial acetic acid, and 60 g of finely pulverized, freshly fused potassium acetate. The reaction mixture is heated to boiling for 2-3 hours under reflux and the crude glycol diacetate is distilled. The distillate is then further treated with 60 g ethylene dibromide and 80 g fused, finely pulverized, fused potassium acetate, and the mixture, as above, heated to boiling for 2-3 hours. The crude glycol diacetate is then again distilled and purified by distillation using efficient fraction column. Three fractions are collected: < 140° C; from 140-175° C and > 175° C. Fractions from 140-175° C and > 175° C are redistilled separately. The pure ethylene glycol diacetate distills between 180-190° C, the main portion at 186° C. The yield of ethylene glycol diacetate is 70 g. Additional 15 g could be obtained by repeating the synthesis with the fraction collected under 180° C.
