酚类衍生物是生物质木质素的模型化合物,也是煤焦油中的重要馏分和废水中的有害物质,通过酚类衍生物催化加氢可以制备环己酮和环己醇,产物环己酮和环己醇(KA油)是合成纤维尼龙6及尼龙66的单体己内酰胺和己二酸的重要原料,同时也是医药、染料等精细化学品的重要中间体[1].因此,酚类衍生物催化加氢制备环己酮和环己醇具有重要的科学意义和应用前景[2-3].目前,生物圈含木质素3×1010t左右,每年再生2×1010t.木质素也
Phenolic derivatives are model compounds of biomass lignin, and are also harmful substances in important fractions of coal tar and waste water. Cyclohexanone and cyclohexanol can be prepared by catalytic hydrogenation of phenolic derivatives, and the product cyclohexanone and Cyclohexanol (KA oil) is an important raw material for caprolactam and adipic acid of synthetic fiber nylon 6 and nylon 66 as well as an important intermediate for fine chemicals such as pharmaceuticals and dyes [1]. Therefore, the phenol derivatives Hydrogenation of cyclohexanone and cyclohexanol has important scientific significance and application prospects [2-3]. At present, the biosphere contains lignin about 3 × 1010t, annual regeneration of 2 × 1010t. Lignin also
