ABSTRACT:
Alcohols may be synthesized by treating an olefinic hydrocarbon with carbon monoxide and hydrogen in a hydroformylation zone using a rhodium complex catalyst and an amine modifier to effect the reaction. Following the formation of the alcohol, a catalyst may be extracted from said alcohol by treatment with an aqueous ammonium hydroxide solution. Following this, the aqueous ammonium solution containing the rhodium catalyst is subjected to an extraction process utilizing the amine modifier as the extractant and thereafter recycling the rhodium complex catalyst and amine modifier to the hydroformylation zone.
