Abstract
Abstract The hydroformylation of olefinic hydrocarbons is effected by treating the hydrocarbon with hydrogen and carbon monoxide in the presence of a catalyst system which comprises a cobalt-containing compound chemically bonded to a zeolite-alumina hydrosol dispersion. The reaction is effected at temperatures ranging from about 70° to about 300° C. and pressures ranging from about 1 to about 500 atmospheres.
