Adipic acid (AA) was obtained by catalyzed oxidation of cyclohexene, epoxycyclohexane, or cyclohexanediol under organic solvent-free conditions using aqueous hydrogen peroxide (30%) as an oxidizing agent and molybdenum- or tungsten-based Keggin polyoxometalates (POMs) surrounded by organic cations or ionically supported on functionalized Merrifield resins. Operating under these environmentally friendly, greener conditions and with low catalyst loading (0.025% for the molecular salts and 0.001⁻0.007% for the supported POMs), AA could be produced in interesting yields.
己二酸(AA)是通过在无有机溶剂条件下,使用 30%过氧化氢水溶液作为氧化剂,催化氧化环己烯、环氧环己烷或环己烷二醇,得到的。所使用的催化剂为多金属氧酸盐(POMs),其由有机阳离子包围或离子负载在功能化的 Merrifield 树脂上。在这些环保、更绿色的条件下,以及低催化剂负载量(分子盐为 0.025%,负载型 POM 为 0.001⁻0.007%)下,己二酸可以以有趣的产率得到。
