Metathesis catalyst and process for use thereof

摘要

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.

1. A process to produce C4 to C24 linear alpha-olefin comprising contacting a feed material with an alkene selected from the group consisting of ethylene, propylene butene, pentene, hexene, heptene, octene, nonene, and mixtures thereof and a metathesis catalyst compound represented by the formula: wherein M is a Group 8 metal from the Periodic Table of the Elements; X and X1 are anionic ligands; L is a neutral two electron donor; L1 is P; R is a C1 to C30 hydrocarbyl or a C1 to C30 substituted hydrocarbyl; G* is selected from the group consisting of hydrogen, a C1 to C30 hydrocarbyl, and a C1 to C30 substituted hydrocarbyl; R1 is selected from the group consisting of hydrogen, a C1 to C30 hydrocarbyl, and a C1 to C30 substituted hydrocarbyl; R2 is selected form the Group consisting of hydrogen, C1 to C30 hydrocarbyl, and C1 to C30 substituted hydrocarbyl; and G is independently selected from the group consisting of hydrogen, halogen, C1 to C30 hydrocarbyls and C1 to C30 substituted hydrocarbyls and wherein the alpha olefin produced has at least one more carbon atom than the alkene, wherein the feed material is a triacylglyceride, fatty acid, fatty acid alkyl ester and fatty acid ester derived from seed oil.
