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.
本文提供了一种制备α,β-不饱和酮的方法,该方法是通过在胺催化剂存在下对甲基酮进行缩合反应实现的。这样的胺催化剂可以被负载在二氧化硅-氧化铝载体上。这样的胺催化剂可以在存在额外酸的情况下使用。α,β-不饱和酮可以通过甲基酮的二聚化和/或三聚化产生。这样的α,β-不饱和酮可适用于生产燃料、汽油添加剂和/或润滑剂,或其前体。甲基酮可以从可再生来源获得,例如通过生物质发酵。
