Abstract:
1. A process for preparing phenol and cyclohexanone, the process comprising: (a) hydro-alkylating benzene with hydrogen or alkylating benzene with cyclohexene in the presence of at least one Y zeolite to form cyclohexylbenzene; (b) selective aerobic oxidation of the cyclohexylbenzene to form a hydroperoxide, wherein the oxidation is catalyzed by at least one N-hydroxy-derivative in the presence of at least one polar solvent; and (c) scission of the hydroperoxide to form phenol and cyclohexanone, wherein the scission is catalyzed by at least one homogeneous or heterogeneous acid catalyst, wherein the hydro-alkylating or alkylating (a) occurs in the presence of a catalytic composition comprising the Y zeolite and an inorganic ligand, the Y zeolite has a crystalline structure with openings consisting of 12 tetrahedra, the inorganic ligand is γ-alumina, the catalytic composition has a pore volume, calculated by summing the mesoporosity and macroporosity fractions, of greater than or equal to 0.7 cm at least 30% of the pore volume consists of pores with a diameter greater than 100 nanometers.
