ABSTRACT:
Propylene glycol and dipropylene glycol diesters are prepared by reacting dichloropropyl ethers with a carboxylic acid salt, e.g., sodium acetate, and the corresponding carboxlyic acid, e.g., acetic acid. The by-product sodium chloride is insoluble in the acetic acid and easily separated from the reaction mixture. The diesters can be hydrolyzed to their respective glycols.
