Abstract
Alcohol may be synthesized from olefinic hydrocarbons by treating the hydrocarbon with carbon monoxide and hydrogen in a hydroformylation zone using 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. The aqueous ammonium hydroxide solution containing the catalyst is then stripped of ammonia by treatment with a stripping agent such as carbon monoxide. A major portion of the alcohol is recovered while the remaining portion is used as an extractant to recover the rhodium complex catalyst from the aqueous ammonium hydroxide solution and thereafter is recycled to the hydroformylation zone.
