WebJul 7, 2010 · An important problem in the processes of catalytic chlorination of chlorobenzene is the preparation of a reaction mixture with the possibility of a high content of para-dichlorobenzene since the demand for it is greater than for ortho-dichlorobenzene.With this objective, Lewis acids (FeCl 3, SbCl 5, AlCl 3, etc.) with sulfur … WebMaking chlorobenzene. Benzene reacts with chlorine in the presence of a catalyst, replacing one of the hydrogen atoms on the ring by a chlorine atom. The reaction happens at room temperature. The catalyst is either aluminium chloride or iron. Strictly speaking iron isn't a catalyst, because it gets permanently changed during the reaction.
