Abstract
An olefin metathesis catalyst consists essentially of a transition metal or oxide thereof supported on a high purity silica support possessing low amounts of acidic or basic sites such that in the reaction of pure butene-1 over said catalyst under metathesis reaction conditions the reaction possesses a weight selectivity to hexene-3 of at least 55 wt %.

A metathesis catalyst consisting essentially of a transition metal or oxide thereof supported on a high purity silica support, said high purity silica support possessing low amounts of acidic or basic sites such that in a reaction of pure 1-butene over said catalyst under metathesis reaction conditions the reaction possesses a weight selectivity to hexene-3 of at least 55 weight percent.
A metathesis process comprising providing a feedstock containing one or more olefins and contacting the feedstock with a metathesis catalyst under metathesis reaction conditions which minimize or eliminate double bond isomerization reactions to provide a metathesis reaction product, wherein the metathesis catalyst consists essentially of a transition metal or oxide thereof supported on a high purity silica support, said high purity silica support possessing low amounts of acidic or basic sites such that in a reaction of pure butene-1 over said catalyst under metathesis reaction conditions the reaction possesses a weight selectivity to hexene-3 of at least 55 weight percent.
