    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 cm /g, wherein at least 30% of said volume consists of pores with a diameter greater than 100 nanometers.
