879. GRESHAM, W. F., BROOKS, R. E., AND GRIGSBY, W. E. (E. I. du Pont de Nemours & Co.). Synthesis of Diethyl Ketone. United States Patent 2,473,995, June 21, 1949: appl. filed June 19, 1946, Serial No. 677,922 (Cl. 260-597). Chem. Abs., vol. 44, 1950, p. 1130.

Diethyl ketone is synthesized by heating a mixture of C₂H₄, CO, and H₂ containing initially more than 1 molecule of C₂H₄ per mol. of H₂ and having an initial CO : H₂ molal ratio of from about 5 : 1-20 : 1 at a reaction temperature of about 50º-350º in the presence of a Co catalyst under a pressure of 325-1,500 atm., and thereafter separating diethyl ketone from the reaction product.
