Abstract:
This invention relates to a Group 8 metal containing catalyst compound for the metathesis of olefins.This invention also relates to process to make alphaolefins comprising contacting an olefin, such as ethylene, with a feed oil containing a triacylglyceride (typically a fatty acid ester (such as methyl oleate)) with a Group 8 metal containing catalyst compound. The fatty acid ester may be a fatty acid methyl ester derived from biodiesel.

Abstract:
This invention relates to processes for increasing the viscosity of an oligomer composition including contacting the oligomer composition comprising one or more vinyl terminated oligomer with a supported mixed metal oxide catalyst; wherein the contacting causes the reaction of the vinyl terminated oligomers; and producing a product oligomer composition having a higher viscosity than the oligomer composition.
Abstract:
This invention relates to a vinyl terminated higher olefin copolymer having an Mn of 300 g/mol or more (measured by 1H NMR) comprising: (i) from about 20 to about 99.9 mol % of at least one C5 to C40 higher olefin monomer; and (ii) from about 0.1 to about 80 mol % of propylene; wherein the higher olefin copolymer has at least 40% allyl chain ends. The copolymer may also have an isobutyl chain end to allyl chain end ratio of less than 0.7:1 and/or an allyl chain end to vinylidene chain end ratio of greater than 2:1.

Abstract:
This invention relates to a process to produce a poly(alpha-olefin)(alpha, internally unsaturated, nonconjugated olefin) comprising: contacting at least one renewable feedstream with at least one lower olefin in the presence of a metathesis catalyst, wherein a mixture of at least one C4 to C40 linear alpha-olefin and at least one alpha, internally unsaturated, nonconjugated olefin is produced; and contacting the mixture with a metallocene catalyst system, wherein a poly(alpha-olefin)(alpha, internally unsaturated, nonconjugated olefin) is produced.
Abstract:
A promoter can have utility in selective heterogeneous oxidation of arylalkyl hydrocarbons such as, for example, cyclohexyl benzene and/or sec-butyl benzene to form hydroperoxides. The promoter can include the product of contacting a solid support comprising a metal oxide surface and an iron compound. The solid support can include, for example, titanium dioxide and/or an iron oxide such as magnetite and can have magnetic susceptibility. A method for the oxidation of arylalkyl hydrocarbons to form hydroperoxides can include contacting 16 an arylalkyl hydrocarbon with oxygen in the presence of the promoter under catalytic oxidation conditions to form arylalkyl hydroperoxide, which can then be converted to phenol via cleavage 26. The method can include recovery 22 of the promoter from the arylalkyl hydroperoxide and can further include recycling the recovered promoter to the contacting 16. Where the solid support has magnetic susceptibility, the recovery 22 can include magnetic separation of the promoter.
