3262. SCHEXNAILDER, R. E. (Standard Oil Development Co.). preparation of an Oxo synthesis Catalyst. United States Patent 2,500,210, Mar. 14, 1950; appl. filed Oct. 31, 1946, Serial No.707,033; 3 claims ( Cl. 252-451). Chem. Abs., vol. 44, 1950, p. 4607.

Silica hydrogel is impregnated with salts of Co,, t, and Cu. these salts are then decomposed on the silica. Thus a Na2O.3.25SiO3 solution of 1.2 sp. gr. is mixed with H2SO4 of 1.12 sp. gr., and the washed hydrogel is mixed with Co(NO₃)₂, Th(NO₃)_4, and Cu(NO₃)₂ by milling. The plasticized mass is heated to 550° F. to decompose the nitrates to oxides. The catalyst is activated at about 850° F. and consists of Si 65, Co 32, Th 5, and Cu 1%.
