Abstract
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.
