    摘要： A process for producing phenol and methyl ethyl ketone comprises contacting benzene and a C4 alkylating agent under alkylation conditions and in the presence of an alkylation catalyst comprising at least one molecular sieve of the MCM-22 family to produce an alkylation effluent comprising secbutylbenzene; wherein the contacting is conducted in a plurality of reaction zones and the C4 alkylating agent secbutylbenzene fraction is recovered from the alkylation effluent and comprises at least 95 wt % sec-butylbenzene, less than 100 wt ppm of C8+ olefins, and less than 0.5 wt % of isobutylbenzene and tert-butylbenzene. The sec-butylbenzene fraction is then oxidized to produce sec-butylbenzene hydroperoxide and the hydroperoxide is cleaved to produce phenol and methyl ethyl ketene.

    摘要： In a process for producing cyclohexylbenzene, benzene and hydrogen are fed to at least one reaction zone comprising a catalyst system which comprises a molecular sieve and at least one hydrogenation metal. The MCM-22 family molecular sieve having an X-ray diffraction pattern including d-spacing maxima at 12.4±0.25, 6.9±0.15, 3.57±0.07 and 3.42±0.07 Angstrom, and the hydrogenation metal is selected from the group consisting of palladium, ruthenium, nickel, zinc, tin, cobalt, and combinations of any two or more thereof. Hydroalkylation conditions of temperature and pressure are selected to produce a hydroalkylation conversion in a range of from about 15% to about 75% The benzene and hydrogen are then contacted in the at least one reaction zone under said selected hydroalkylation condition to produce an effluent containing cyclohexylbenzene.
