标题:乙酰丙酸衍生的戊酸转化为煤油型液体运输燃料
摘要:在木质纤维素生物质向燃料和化学物质的转化中,非常需要形成碳碳键和增加疏水性.酮基脱羧完全符合这些要求,因为它将羧酸转化为形成一个碳碳键的酮,并消除了三个氧原子,如二氧化碳和水.该反应以级联方法与氢化和脱水催化剂一起用于从己糖衍生的戊酸获得煤油范围内的烃.结果表明,氧化锆对于该方法是非常选择性和稳定的催化剂,当与负载在氧化铝上的铂结合使用时,氧含量几乎降至零.此外,已证明氧化铝优于活性炭,二氧化硅,氧化锆或氧化锆作为加氢/脱水/加氢顺序的载体,并且钯基催化剂的失活速度比铂催化剂快.因此,在优化的反应条件下,戊酸被转化为在有机液相中具有80%选择性的正壬烷(连同10%的c 10-C 15碳氢化合物),进料与催化剂之比[w / W]高达100:1.模拟蒸馏证明,无氧烃产物混合物(85%的收率)与煤油的沸点范围非常吻合.在气相中,检测到丁烷和主要是二氧化碳.

标题:Method for synthesis of ketones from plant oils

摘要:Ketones may be produced in high yields from glycerides of short chain fatty acids by reaction with a carboxylic acid. The reaction is conducted in the presence of a catalyst and under conditions effective for ketonization of decanoate with the carboxylic acid to produce free ketones. Reaction of a glyceride comprising at least one ester of decanoic acid with a carboxylic acid selected from acetic acid and/or propionic acid produces 2-undecanone and/or 3-dodecanone, respectively. Catalysts of the formula Fe m Ce n Al p O x , wherein m is between about 0.2 to about 0.6, n is about 0.2, p is between about 0.6 to about 0.2, and x is greater than 0, produce significantly higher yields of the ketones than other known metal oxides.

摘要:A facile solvothermal method can be used to synthesize metal alkanoate nanoparticles using a metal nitrate precursor, alcohol/water, and alkanoic acid. The method can produce lanthanide (e.g., La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, or Yb) and transition metal (e.g., Ag, Co, Cu, or Pb) alkanoate nanoparticles (<100 nm) with spherical morphology. These hybrid nanomaterials adopt a lamellar structure consisting of inorganic metal cation layers separated by an alkanoate anion bilayer and exhibit liquid crystalline phases during melting. The metal alkanoate nanoparticles can be calcined to produce metal oxide nanoparticles.
