摘要: It has been discovered that heating C.sub.4 -C.sub.17 internal olefins to 300.degree.F to 500.degree.F for about 15 to 30 minutes in the presence of an oxo catalyst prior to hydroformylation results in a higher selectivity to primary alcohols than does the conventional hydroformylation procedure of heating all the reactants together.

摘要: Disclosed is a process for separating unreacted olefins, paraffins, aldehydes and alcohols from the catalyst and heavy ends from the hydroformylation process by using thin film distillation. In this process, the crude oxo product is metered into a thin film evaporator wherein the distillate containing olefins, paraffins, aldehydes and alcohols is rapidly separated by a continuous wiping action from the residue which contains the catalyst complex and the heavy ends. The various products are fractionated while the residue is directly recycled.

摘要: A hydroformylation process for increasing the yield of straight chain unsubstituted primary alcohols from predominantly terminal olefins by contacting the olefins with carbon monoxide and hydrogen in the presence of a cobalt catalyst is characterized by the incorporation of aqueous base in a base to cobalt molar ratio of about 10:1 to 20:1 in the reaction mixture before or after heating the same to reaction temperature. The base introduced in the oxo reactor while hydroformylation is occurring continuously converts by-products acetals and esters to the corresponding primary alcohols, thereby considerably increasing the yield thereof.
