Patent number: 10906861Abstract: Described are methods of making organic compounds by metathesis chemistry. The methods of the invention are particularly useful for making industrially-important organic compounds beginning with starting compositions derived from renewable feedstocks, such as natural oils. The methods make use of a cross-metathesis step with an olefin compound to produce functionalized alkene intermediates having a pre-determined double bond position. Once isolated, the functionalized alkene intermediate can be self-metathesized or cross-metathesized (e.g., with a second functionalized alkene) to produce the desired organic compound or a precursor thereto. The method may be used to make bifunctional organic compounds, such as diacids, diesters, dicarboxylate salts, acid/esters, acid/amines, acid/alcohols, acid/aldehydes, acid/ketones, acid/halides, acid/nitriles, ester/amines, ester/alcohols, ester/aldehydes, ester/ketones, ester/halides, ester/nitriles, and the like.Type: GrantFiled: April 3, 2015Date of Patent: February 2, 2021Assignee: Wilmar Trading Pte LtdInventors: Timothy W. Abraham, Hiroki Kaido, Choon Woo Lee, Richard L. Pederson, Yann Schrodi, Michael John Tupy

Publication number: 20150094481Abstract: The invention is directed to methods of making organic compounds by metathesis and hydrocyanation. Hydrocyanation functions to introduce a nitrile group into the organic compound. The nitrile group may be converted into an amine group, an aldehyde group, an alcohol group, or a carboxylic acid group. The method of the invention may be used, for example, to make industrial important organic compounds such as diacids, diesters, acid-amines, acid-alcohols, acid-nitriles, ester-amines, ester-alcohols, and ester-nitriles.Type: ApplicationFiled: October 13, 2014Publication date: April 2, 2015Applicant: ELEVANCE RENEWABLE SCIENCES, INC.Inventors: Timothy W.

Patent number: 8614344Abstract: Disclosed are improved methods for conducting metathesis utilizing polyunsaturated fatty acid compositions (e.g., polyunsaturated fatty acid polyol esters, polyunsaturated fatty acids, polyunsaturated fatty esters, and mixtures), such as those found in naturally occurring oils and fats, as the starting material. The inventive methods involve hydrogenation of polyunsaturated fatty acid compositions prior to metathesis, thereby providing partially-hydrogenation compositions having a relatively higher amount of monounsaturated fatty acid species. The partially hydrogenated composition can then be subjected to metathesis to provide a metathesis product composition containing industrially useful compounds.Type: GrantFiled: October 15, 2007Date of Patent: December 24, 2013Assignee: Elevance Renewable Sciences, Inc.Inventors: Hiroki Kaido, Michael John Tupy, Richard L.
