Conditions

Temperature
150 °C

Procedure

Propylene and oxygen were introduced, in the manner described in Example 1, into a solution of 500 ml glacial acetic acid and 50 ml acetic anhydride containing 2 g aluminum acetate and 2 g cupric chloride. The contents were then heated to approximately 150°C. After cooling and release of pressure, the contents were subjected to distillation. 30.6 g propylene glycol diacetate were obtained.
