Answer:
The production of styrene increased dramatically during the 1940s, when it was used as a feedstock for synthetic rubber. Because styrene is produced on such a large scale, ethylbenzene is in turn prepared on a prodigious scale (by alkylation of benzene with ethylene).
Explanation:
Styrene is produced predominately by ethylbenzene (EB)-based technology. EB is first made by the catalytic alkylation of benzene with ethylene, using either aluminium chloride or, more recently, zeolite catalysts
