    摘要： Process for the preparation of phenol and cyclohexanone which comprises: a. the synthesis of cyclohexylbenzene by the hydro-alkylation of benzene by contact with hydrogen or the alkylation of benzene with cyclohexene using Y zeolites; b. the selective aerobic oxidation of cyclohexylbenzene to the corresponding hydroperoxide catalyzed by N-hydroxy-derivatives in the presence of polar solvents; and c. the scission of the hydroperoxide of cyclohexylbenzene to phenol and cyclohexanone by homogeneous or heterogeneous acid catalysts; characterized in that the synthesis of cyclohexylbenzene takes place in the presence of a catalytic system comprising a Y zeolite and an inorganic ligand wherein the Y zeolite has a crystalline structure with openings consisting of 12 tetrahedra and the inorganic ligand is γ-alumina, and wherein said catalytic composition is characterized by a pore volume, obtained by adding the mesoporosity and macroporosity fractions, greater than or equal to 0.7 cm3/g, wherein at least 30% of said volume consists of pores with a diameter greater than 100 nanometers.

    摘要翻译： 苯酚和环己酮的制备方法，其包括：a。 通过与氢气接触或通过使用Y沸石与苯与环己烯进行烷基化反应来合成环己基苯; b。 在极性溶剂存在下，由N-羟基衍生物催化环己基苯与相应的氢过氧化物的选择性好氧氧化; 和c。 通过均相或多相酸催化剂将环己基苯的氢过氧化物分解成苯酚和环己酮; 其特征在于环己基苯的合成是在包含Y沸石和无机配体的催化体系的存在下进行的，其中Y沸石具有由12面四面体构成的开口的结晶结构，无机配体是γ-氧化铝，其中所述 催化组合物的特征在于通过加入大于或等于0.7cm 3 / g的介孔和大孔隙度级分获得的孔体积，其中至少30％的所述体积由直径大于100纳米的孔组成。
