ketonization of crotonic acid. The main aromatic compounds are formed in stage (3) from propylene and 2,3-dimethyl-2-cyclopenten-1-one as two key intermediates, the former from decarboxylation and the latter from ketonization of crotonic acid. The reaction routes reveal that the formation of aromatics is affected to a great extent by the concentrations of phosphoric acid and water in the reaction, which
聚(3-羟基丁酸酯)或PHB是微生物的能量存储材料,可以重整为富含芳族化合物的烃油。这项工作研究了从PHB到关键中间体和最终碳氢化合物的主要反应路线。在中等温度(200–230°C)下催化磷酸的主要顺序反应包括:(1)PHB分解为巴豆酸,主要的单体中间体,(2)巴豆酸脱氧,以及(3)组合脱氧分子。PHB中的氧气以CO 2和H 2的形式除去在步骤(2)中的O,涉及巴豆酸的脱羧和酮化。主要的芳族化合物是在阶段(3)中由丙烯和2,3-二甲基-2-环戊烯-1-酮作为两个关键中间体形成的,前者来自脱羧作用,后者来自巴豆酸的酮化作用。反应路线表明,反应中磷酸和水的浓度在很大程度上影响芳烃的形成,可用于控制烃油的组成。
