Patent Abstracts

Primary alcohols are prepared by reacting an olefinic hyrocarbon (propylene, butanes, butadiene, vinyl acetylene, cyclohexene, and hexenes) having 2-30 C atoms per molecule with CO and H₂ at 250º-400º and 325-1,500 atm. The initial mol ratio of CO:H₂ should lie 2:1-1:2. For maximum production of alcohol and efficient absorption of exothermic heat, the amount of H₂O present should be controlled 0.1-1.5 parts, by weight, per part of olefin. A Co salt (Chloride, sulfate, nitrate, acetate, propionate, and naphthenate) preferentially soluble in the olefinic reactant is present as the catalyst. The amount of catalyst per unit weight of olefin should be as low as 0.005-2.0%. Use of the catalyst in solution suppresses the hydrogenation of olefin hydrocarbons to alkalines and the formation of other byproducts.
