Abstract

Provided herein are methods for producing α,β-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 α,β-unsaturated ketones may be produced by dimerization and/or timerization of the methyl ketones. Such α,β-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.
