    摘要: In a process for producing cyclohexylbenzene, benzene is reacted with cyclohexene in a first reaction zone under conditions effective to produce a reaction product comprising cyclohexylbenzene and at least one polycyclohexylbenzene. At least a portion of the reaction product and a stripping agent comprising at least one C1 to C11 hydrocarbon or hydrogen are then separately supplied to a separation device and separated into at least a first fraction rich in cyclohexylbenzene and a second fraction rich in the at least one polycyclohexylbenzene.

    摘要: Disclosed herein is a process for producing phenol. The process includes oxidizing at least a portion of a feed comprising cyclohexylbenzene to produce an oxidation composition comprising cyclohexyl-1-phenyl-1-hydroperoxide. The oxidation composition may then be cleaved in the presence of an acid catalyst to produce a cleavage reaction mixture comprising the acid catalyst, phenol and cyclohexanone. At least a portion of the cleavage reaction mixture may be neutralized with a basic material to form a treated cleavage reaction mixture. In various embodiments, the treated cleavage reaction mixture contains no greater than 50 wppm of the acid catalyst or no greater than 50 wppm of the basic material.

    摘要: In a process for producing cyclohexylbenzene, benzene is contacted with hydrogen under hydroalkylation conditions effective to form a first effluent stream comprising cyclohexylbenzene, cyclohexane, methylcyclopentane, and unreacted benzene. At least a portion of the first effluent stream is contacted with a dehydrogenation catalyst under dehydrogenation conditions to convert at least a portion of the cyclohexane to benzene thereby forming a second effluent stream. The amount of methylcyclopentane in the second effluent stream is different by no more than 65% of the total amount of the portion of the first effluent stream, said amounts being on a weight basis. A methylcyclopentane-containing stream is removed from either the first or the second effluent stream and at least a portion of the second effluent stream containing benzene is recycled to the hydroalkylation step.

    摘要: In a process for producing phenol, cyclohexylbenzene hydroperoxide is cleaved to produce a cleavage effluent stream comprising phenol and cyclohexanone and at least a portion of the cleavage effluent stream is fractionated to produce a first fraction richer in cyclohexanone than the cleavage effluent stream portion and a second fraction richer in phenol and depleted in cyclohexanone as compared with said cleavage effluent stream portion. At least a portion of the second fraction is then contacted with a dehydrogenation catalyst in a dehydrogenation reaction zone under dehydrogenation conditions effective to convert at least a portion of the cyclohexanone in said second fraction portion into phenol and cyclohexanol.
