ABSTRACT:
Alcohol may be synthesized by treating olefinic hydrocarbons with carbon monoxide and hydrogen in a hydroformylation zone utilizing a rhodium complex catalyst to effect the reaction. Following formation of the alcohol, the catalyst may be extracted from the alcohol by treatment with an aqueous ammonium hydroxide solution. Thereafter the aqueous ammonium hydroxide solution containing the catalyst is then stripped of ammonia by treatment with carbon monoxide or carbon monoxide containing gas. The aqueous ammonium hydroxide solution containing the rhodium complex catalyst is then stripped of a portion of water and the remaining solution is thereafter recycled to the hydroformylation zone.
