An ethylbenzene production method is applied using a mixed phase ethylation of dilute ethylene with impure benzene. The benzene feed contains over 75% by weight benzene, with the balance being non-aromatic C6 to C7 hydrocarbons, including cyclohexane. The production method involves separating the benzene vapor from the hydrogen/methane rich vent gas by condensing the benzene at a temperature below about 5.5 DEG C., the normal freezing point of benzene.
