Abstract: Internally unsaturated near linear oligomers of lower olefins are converted into alpha olefins, or 1-alkenes, of essentially the same degree of linearity. The internally unsaturated olefins are the product of lower alkene oligomerization using a surface deactivated zeloite, such as ZSM-5 or ZSM-23, and contain about 1 to 2 methyl branches per twelve (12) carbon atoms. The feedstock is converted to alpha olefin oligomers which also contain approximately 1 to 2 methyl branches per thirteen (13) carbon atoms. The conversion is achieved by hydroformylation of the near linear internal olefins to provide a novel 1-alkanol oligomer structure without further branching of the carbon oligomeric chain. Acetylation of the 1-alkanol followed by deesterification by pyrolysis provides the sought for near linear 1-alkene. The near-linear oligomers of lower olefins so produced comprise vinyl hydrocarbon monomers that can be further oligomerized by cationic and coordination catalysts.

Oligomerization of the aforementioned alpha olefins using reduced valence state Group VIB metal oxide catalyst on porous support provides a hydrocarbon lubricant with a viscosity index of greater than 130 at 100.degree.
