Benzene → Cyclohexylbenzene

Participants

Reaction Steps

Referring to an embodiment of the invention illustrated in FIG. 2, hydrogen (e.g., fresh hydrogen) and benzene (e.g., fresh benzene) are supplied by lines 11 and 12 and are combined in line 13 before being fed to a heater 14 where the temperature of the reagents is increased to the desired reaction temperature. The heated feed is then fed by line 15 to a reactor 16 which contains hydroalkylation catalyst 17 and which is operated under conditions to vaporize part of the benzene feed and produce a mixed phase product effluent in which most of cyclohexylbenzene is in the liquid phase and a portion of the benzene is in the vapor phase. The effluent leaves the reactor 16 through line 18 and is fed to a flash drum 19, which separates the effluent into a liquid stream and a vapor stream.
