Patent number: 10138193Abstract: Provided herein are methods for producing ?,?-unsaturated ketones from the condensation of methyl ketones in the presence of an amine catalyst. Such amine catalysts may be supported, for example, on a silica-alumina support. Such amine catalysts may be used in the presence of an additional acid. The ?,?-unsaturated ketones may be produced by dimerization and/or timerization of the methyl ketones. Such ?,?-unsaturated ketones may be suitable for use in producing fuels, gasoline additives, and/or lubricants, or precursors thereof. The methyl ketones may be obtained from renewable sources, such as by the fermentation of biomass.Type: GrantFiled: October 28, 2015Date of Patent: November 27, 2018Assignees: The Regents of the University of California, BP Corporation North America Inc.Inventors: Shylesh Sankaranarayanapillai, Sanil Sreekumar, F.
