Patent number: 5072057Abstract: A catalytic process for the hydroformylation of olefinic, sulfur containing thermally cracked petroleum streams to produce aldehydes and/or alcohols is disclosed. The catalysts are homogeneous transition metal carbonyl complexes. Especially preferred catalysts for low and medium pressure hydroformylation are cobalt and rhodium carbonyl hydride complexes in which some of the carbonyl ligands have been replaced by trivalent phosphorus ligands. In a preferred high pressure hydroformylation, the sulfur-containing naphtha and gas oil distillate feeds are produced from vacuum residua by high temperature thermal cracking. Such feeds contain more than 20% olefins with 1-n-olefins as the single major types. These olefin components are hydroformylated in the presence of a cobalt carbonyl complex to produce a novel type of semilinear aldehyde and/or alcohol product containing an average of less than one alkyl branch per molecule.Type: GrantFiled: January 22, 1991Date of Patent: December 10, 1991Assignee: Exxon Research & Engineering Co.Inventors: Alexis A.
