A process for producing phenol and methyl ethyl ketone comprises contacting benzene with a Calkylating agent under alkylation conditions with catalyst comprising zeolite beta or a molecular sieve having an X-ray diffraction pattern including d-spacing maxima at 12.4&#xb1;0.25, 6.9&#xb1;0.15, 3.57&#xb1;0.07 and 3.42&#xb1;0.07 Angstrom to produce an alkylation effluent comprising sec-butylbenzene. The sec-butylbenzene is then oxidized to produce a hydroperoxide and the hydroperoxide is decomposed to produce phenol and methyl ethyl ketone.

Process for producing phenol and methyl ethyl ketone

The present invention provides a process for producing a monoalkylated aromatic compound, particularly cumene, comprising the step of contacting a polyalkylated aromatic compound with an alkylatable aromatic compound under at least partial liquid phase conditions and in the presence of a transalkylation catalyst to produce the monoalkylated aromatic compound, wherein the transalkylation catalyst comprises a mixture of at least two different crystalline molecular sieves, wherein each of said molecular sieves is selected from zeolite beta, zeolite Y, mordenite and a material having an X-ray diffraction pattern including d-spacing maxima at 12.4&#xb1;0.25, 6.9&#xb1;0.15, 3.57&#xb1;0.07 and 3.42&#xb1;0.07 Angstrom.

Alkylaromatics production

There is described a process and a catalyst for the hydroalkylation of an aromatic hydrocarbon, particularly benzene, wherein the catalyst comprises a first metal having hydrogenation activity and a crystalline inorganic oxide material having a X-ray diffraction pattern including the following d-spacing maxima 12.4&plusmn;0.25, 6.9&plusmn;0.15, 3.57&plusmn;0.07 and 3.42&plusmn;0.07.

Hydroalkylation of aromatic hydrocarbons

There is described a process the hydroalkylation of an aromatic hydrocarbon, particularly benzene, to produce a cycloalkyl-substituted aromatic compound, particularly cyclohexylbenzene, comprising the step of contacting the aromatic hydrocarbon with hydrogen in the presence of a catalyst comprising MCM-68 and at least one metal having hydrogenation activity.

There is described a process for the transalkylation of a polycycloalkyl aromatic compound, particularly the transalkylation of dicyclohexylbenzene to produce monocyclohexylbenzene. The process comprises contacting the polycycloalkyl aromatic compound with benzene in the presence of a catalyst selected from the group consisting of an acidic solid comprising a Group IVB metal oxide modified with an oxyanion of a Group VIBA metal oxide, TEA-mordenite, zeolite beta and a porous crystalline material having an X-ray diffraction pattern including d-spacing maxima at 12.4&plusmn;0.25, 6.9&plusmn;0.15, 3.57&plusmn;0.07 and 3.42&plusmn;0.07 Angstrom. Preferably the catalyst is a WO /ZrO material.

Production of monocycloalkyl aromatic compounds

This invention relates to a new synthetic porous crystalline material, designated MCM-68, a method and novel polycyclic organic cation for its preparation and its use in catalytic conversion of organic compounds. The new crystalline material exhibits a distinctive X-ray diffraction pattern and has a unique crystal structure which contains at least one channel system, in which each channel is defined by a 12-membered ring of tetrahedrally coordinated atoms, and at least two further, independent channel systems, in each of which each channel is defined by a 10-membered ring of tetrahedrally coordinated atoms, wherein the number of unique 10-membered ring channels is twice the number of 12-membered ring channels.

Synthetic porous crystalline MCM-68, its synthesis and use
