  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。

  Provided are: a powdered material for slush molding; and a manufacturing process therefor. The powdered material is less odorous, exhibits excellent powder fluidity, and does not suffer from troubles resulting from the sliding-down or agglomeration of a pigment even when the resin particles have been pigmented on the surfaces thereof. Thus, the powdered material ensures high productivity. The powdered material is a powdered polyurethane urea resin composition which comprises (D) a polyurethane urea resin that has a total content of bimolecular condensate of acetone, bimolecular condensate of methyl ethyl ketone, and bimolecular condensate of methyl isobutyl ketone of 1,000ppm, or less and (N) an additive, wherein the polyurethane urea resin (D) takes the form of thermoplastic polyurethane urea resin particles (P) that have a volume-mean particle diameter of 20 to 500µm and that have protrusions and recesses on the surfaces. The powdered polyurethane urea resin composition is manufactured by a manufacturing process which includes a step of mixing (A) an isocyanato-terminated urethane prepolymer with (B) an alicyclic diamine and/or an aliphatic diamine in an aqueous medium by stirring to form the resin particles (P).
