Abstract	In a process for producing phenol, benzene is hydroalkylated with hydrogen in the presence of a catalyst under conditions effective to produce a hydroalkylation reaction product comprising cyclohexylbenzene and cyclohexane. At least a portion of the cyclohexane from said hydroalkylation reaction product is then dehydrogenated to produce a dehydrogenation effluent comprising benzene, toluene and hydrogen. At least a portion of the dehydrogenation effluent is washed with a benzene-containing stream to transfer at least a portion of the toluene from the dehydrogenation effluent to the benzene-containing stream.
