Abstract: 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pressure hydroformylation are cobalt and rhodium carbonyl hydride complexes in which some of the carbonyl ligands have been replaced by trivalent phosphorus ligands.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.

Abstract: A multistep process is disclosed for the manufacture of synthetic lubricants from the C.sub.8 to C.sub.24 linear olefin components of below liquid fuel value petroleum distillate fractions derived via the high temperature thermal cracking of petroleum residua. Such feeds contain major amounts of 1-n-olefins, n-paraffins and greater than 0.1% concentration of sulfur mostly in the form aromatic, thiophene type sulfur compounds.In the first step of the present process such feeds are enriched in the straight chain aliphatic hydrocarbon components by one or more separation processes, preferably via urea adduction or by crystallization. In the second step, the olefin components are oligomerized to sulfur containing C.sub.30 to C.sub.60 polyolefins, preferably in the presence of BF.sub.3 complex catalysts. In the third step, the polyolefins are hydrogenated to novel isoparaffin lubricants in the presence of sulfur resistant catalysts, preferably transition metal sulfides.

Abstract: Compositions of matter are disclosed which are highly useful in hydroformylation processes. The compositions are non-charged, non-chelated bis- and tris-(alkyl diaryl phosphine) rhodium carbonyl hydrides. The substituents of the alkyl group include heteroorganic radicals containing silane, silicone, ether, ester, keto and hydroxy oxygen, phosphine oxide and phosphorus ester phosphorus, amine, amide, amine oxide and heterocyclic nitrogen groups.These compositions are highly stable and selective catalysts for the hydroformylation of olefins under certain conditions. The disclosed catalyst systems contain a large excess of phosphine ligand and employ alpha-olefin plus synthesis gas reactant mixtures having a high H.sub.2 /CO ratio at relatively low pressures. They produce mostly aldehydes derived from terminal attack on the alpha-olefin reactant.

Abstract: Certain triarylphosphine rhodium carbonyl hydride complexes(Ar.sub.3 P).sub.3 Rh(CO)H (I) and (Ar.sub.3 P).sub.2 Rh(CO).sub.2 H (II)are selective and stable catalysts of high temperature olefin hydroformylation. The critical factors are the maintenance of a sufficient CO partial pressure, above 25 psia, and the provision of a high excess of triarylphosphine ligand concentration, at a minimum of 1 mole per kg. To provide a high ratio of n- to i-aldehyde products of 1-olefin hydroformylation, the concentration of the tris-phosphine complex (I) is maximized. In a continuous product flashoff operation of the present process, the major high boiling solvent components are the excess phosphine ligands and monoalcohol and monoester by-products.A combined isomerization-hydroformylation process is also disclosed for the selective conversion of internal linear olefins to terminal n-aldehydes. In this process, the concentration of the bis-phosphine complex (II) is minimized.
