    摘要： In a process for preparing an alkylaromatic hydrocarbon composition an olefinic hydrocarbon mixture and an aromatic compound are contacted under alkylation conditions with an aromatic alkylation catalyst selected from a homogeneous acid catalyst and heterogeneous acid catalyst comprising a 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 Angstroms. The olefinic hydrocarbon mixture comprises at least 5 wt % by weight of mono-olefin oligomers of the empirical formula: CnH2n wherein n is greater than or equal to 10, the mono-olefin oligomers comprising at least 20 percent by weight of olefins having at least 12 carbon atoms, and the olefins having at least 12 carbon atoms having an average of from 0.8 to 2.0 C1-C3 alkyl branches per carbon chain. Sulfonation of the alkylaromatic hydrocarbon product produces an alkylaryl sulfonate mixture that exhibits advantageous properties, such as biodegradability and hard and cold water performance.

    摘要： In a process for producing cyclohexylbenzene, benzene and hydrogen are fed to at least one reaction zone. The benzene and hydrogen are then contacted in the at least one reaction zone under hydroalkylation conditions with a catalyst system comprising a 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 at least one hydrogenation metal to produce an effluent containing cyclohexylbenzene. The ratio of the total number of moles of hydrogen fed to said at least one reaction zone to the number of moles of benzene fed to said at least one reaction zone is between 0.4 and 0.9:1.

    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 ketone.
