    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： A process for producing sec-butylbenzene comprises feeding reactants comprising benzene and a C4 olefin to a distillation column reactor having a first reaction zone containing an alkylation catalyst and a second distillation zone, which is located below said first reaction zone and which is substantially free of alkylation catalyst, wherein the ratio of the number of distillation stages in said first reaction zone to the number of distillation stages in said second distillation zone is less than 1:1. Concurrently in the distillation column reactor, the reactants are contacted with the alkylation catalyst in the first reaction zone under conditions such that the C4 olefin reacts with the benzene to produce sec-butylbenzene and the sec-butylbenzene is fractionated from the unreacted C4 olefin. The sec-butylbenzene thereby passes as a liquid phase stream from the first reaction zone to the second distillation zone and the liquid phase stream is withdrawn from the distillation column reactor as bottoms.
