Methods for treating substrates prior to metathesis reactions, and methods for metathesizing substrates

摘要

A method for treating a substrate prior to a metathesis reaction includes treating the substrate with a first agent configured to mitigate potentially adverse effects of one or more contaminants in the substrate on a catalyst used to catalyze the metathesis reaction. The treating reduces a level of the one or more contaminants by an amount sufficient to enable the metathesis reaction to proceed at a substrate-to-catalyst molar ratio of at least about 7,500 to 1. Methods for metathesizing substrates are described.

1. A method of chemically treating a metathesis substrate, comprising:
providing a composition comprising a metathesis substrate and one or more catalyst poisoning contaminants, wherein the metathesis substrate is a natural oil; and treating the composition to reduce the concentration of at least one of the one or more catalyst poisoning contaminants in the composition; wherein the treating comprises contacting the composition with a metal alkyl compound.
