Process for Producing Cyclohexylbenzene |
abstract |
In a process for producing cyclohexylbenzene, hydrogen and benzene are introduced to a first hydroalkylation reaction zone which contains a hydroalkylation catalyst and which is operated under at least partly liquid phase conditions sufficient to effect hydroalkylation of benzene to produce a mixed liquid/vapor phase effluent comprising cyclohexylbenzene and unreacted benzene, wherein at least a portion of the unreacted benzene is in the vapor phase. At least a portion of the effluent is cooled to condense a liquid phase stream containing at least some of the cyclohexylbenzene in the effluent portion and leave a residual stream containing at least some of the unreacted benzene and cyclohexylbenzene. At least a portion of the liquid stream is recycled to the first hydroalkylation reaction zone or to contact the mixed phase effluent exiting the first hydroalkylation reaction zone. Other methods of cooling the reaction effluent are disclosed. |
