Use

Ethylbenzene is currently used on a large scale industrially for the production of styrene monomer. Ethylbenzene may be produced by a number of chemical processes but one process which has achieved a significant degree of commercial success is the alkylation of benzene with ethylene in the presence of a solid, acidic zeolite catalyst. A preferred catalyst includes the synthetic zeolite identified in this specification as MCM-22.In the production of ethylbenzene by this process; ethylene is used as the alkylating agent and is reacted with benzene in the presence of the catalyst at certain temperatures. Production of ethylbenzene involves the liquid-phase reaction of ethylene with benzene C2H4 + C6H6 C8H10 Undesirable reaction occurred by the formation of Di-ethyl benzene from reaction of ethylbenzene with ethylene. C8H10 + C2H4 C10H14 A third reaction also occurs, in which Di-ethyl benzene reacts with benzene to form ethylbenzene. C10H14 + C6H6 2C8H10
