Ethylene and benzene reaction
WebQuestion: The production of ethylbenzene, a very popular industrial chemical, is carried out reacting benzene with ethylene in liquid phase. This reaction takes place in a series of reactors that involve multiple side reactions and intermediates. Ethylene, being the limiting reactant, is used up first and hence a considerable amount of benzene remains unreacted.
