  • Patent number: 9518002
    Abstract: Methods of carrying out metathesis reactions of natural oil-derived polyenes (e.g., dienes and trienes), including functionalized polyenes, are generally disclosed herein. In some embodiments, the dienes or trienes contain a terminal carbon-carbon double bond, and the metathesis reaction is selective toward reaction of the terminal carbon-carbon double bonds in the polyene. Compounds made by such methods are also generally disclosed herein.
    Type: Grant
    Filed: October 19, 2015
    Date of Patent: December 13, 2016
    Assignee: Elevance Renewable Sciences, Inc.
    Inventors: Keith M. Wampler, Jane Uy, Steven A. Cohen
  • Patent number: 9388097
    Abstract: 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.

  • Publication number: 20150274619
    Abstract: Unsaturated alcohol compositions are obtained by reducing a metathesis-derived hydrocarbyl unsaturated ester. Also disclosed is a process for preparing an unsaturated alcohol composition, where a metathesis derived hydrocarbyl carbonyl compound is reacted in the presence of a silane compound, an organic solvent, and a catalyst system prepared from a metallic complex and a reducing agent. This mixture is then hydrolyzed with a metallic base, and then mixed with organic solvent. The resultant mixture is then separated, washed, dried, and/or purified to produce the unsaturated alcohol composition. The unsaturated alcohol derivatives are useful in many end-use applications, including, for example, lubricants, functional fluids, fuels, functional additives for such lubricants, functional fluids and fuels, plasticizers, asphalt additives, friction reducing agents, plastics, and adhesives.
