US Classification:

568385, 568768, 568798

Abstract:

A process for producing phenol and methyl ethyl ketone comprises contacting benzene and a Colefin under alkylation conditions and in the presence of an alkylation catalyst to produce an alkylation effluent comprising sec-butylbenzene and C+ olefins. The alkylation effluent is then treated to reduce the amount of said C+ olefins and produce a treated effluent, whereafter the sec-butylbenzene in the treated effluent is oxidized to produce a hydroperoxide and the hydroperoxide is cleaved to produce phenol and methyl ethyl ketone.

Abstract:

A process for producing phenol and methyl ethyl ketone comprises contacting benzene and a Calkylating 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 C+ 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.

US Classification:

568361, 568798, 585446, 585467

Abstract:

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. 40. 25, 6. 90. 15, 3. 570. 07 and 3. 420. 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.

US Classification:

568385, 568798, 585446, 585448, 585467

Abstract:

A process for producing sec-butylbenzene comprises feeding reactants comprising benzene and a Colefin 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 reactor, the reactants are contacted with the alkylation catalyst in the first reaction zone under conditions such that the Colefin reacts with the benzene to produce sec-butylbenzene and the sec-butylbenzene is fractioned from the unreacted Colefin. The sec-butylbenzene thereby passes as a liquid phase stream from the first reaction zone to the second distillation zone and the liquid phase steam is withdrawn from the distillation column reactor as bottoms.
