Procedure
2 g silicon tetrachloride were dissolved together with 2 g cuprous chloride and 2 g cupric chloride in 500 ml glacial acetic acid and 50 ml acetic anhydride. This solution was saturated with propylene and with compressed air at 40 atmospheres, and then heated to 160°C. Distillation resulted in the preparation of 4.6 g propylene glycol diacetate.
