Abstract
Production of ethylene glycol diacylate by reacting ethylene, divalent mercury compound and an aliphatic acid to produce an acyloxyethylmercuric acylate and disproportionating said acyloxyethylmercuric acylate by heating in the presence of a catalytic concentration of perchloric acid to form an ethylene glycol diacylate and lactone. When the acyloxyethylmercuric acylate is acyloxyethylmercuric acetate, the disproportionation produces gamma-butyrolactone as the lactone.
