Procedure
1 g of tantalum-V-chloride was dissolved in 400 ml of glacial acetic acid and 50 ml of acetic acid anhydride. After saturation with propylene and the further introduction under pressure of about 10 atmospheres of propylene, 20 atmospheres of oxygen were additionally added and the mixture was heated to about 140° C. After cooling, the batch was distilled. 20 g of propylene glycol diacetate were formed.
