processes of catalytic homocondensation of methyl ethyl ketone (MEK) in the presence of basic and acid heterogeneous catalysts were studied. A Pd/activated carbon catalytic system was proposed for coupling the processes of MEK condensation and hydrogenation of its products. It was found that high selectivity (more than 90%) for the sum of two condensation/hydrogenation products (5-methylheptan-3-one and 3-methylheptane)
研究了在碱性和酸性非均相催化剂存在下甲基乙基酮(MEK)的催化均聚反应过程。提出了一种 Pd/活性炭催化体系,用于偶联 MEK 缩合和产物加氢过程。研究发现,在氢气气氛中,两种缩合/加氢产物(5-甲基庚烷-3-酮和 3-甲基庚烷)的总和可实现高选择性(超过 90%),MEK 转化率高达 43 %。
