The chemical uses for ethylene prior to World War II were limited, for the most part, to ethylene glycol and ethyl alcohol. After the war, the demand for styrene and polyethylene took off, stimulating ethylene production and olefin plant construction. Todays list of chemical applications for ethylene reads like the WTiat s What of petrochemicals polyethylene, ethylbenzene (a precursor to styrene), ethylene dichloride, vinyl chloride, ethylene oxide, ethylene glycol, ethyl alcohol, vinyl acetate, alpha olefins, and linear alcohols are some of the more commercial derivatives of ethylene. The consumer products derived from these chemicals are found everywhere, from soap to construction materials to plastic products to synthetic motor oils. 

On the basis of products formed in a number of condensation reactions only confusion results for any step by step mechanism involving specific identifiable species as intermediates. Here are some of the facts. Benzene condenses with cyclopropane to form n-propylbenzene (Simons et al., 44). Normal propyl bromide gives chiefly isopropyl benzene (Simons and Archer, 36) as does propylene (Simons and Archer, 28). Ethyl alcohol gives ethylbenzene, but methyl alcohol does not give...

Even (hough there are few direct end-uses foe ethylene, it is probably the most important petrochemical feedstock, both in terms of quantities used and economic value. Ethylene is the feedstock for ethylene oxide, ethylbenzene, ethyl chloride, elhylene dichloride, ethyl alcohol, and polyethylene, most of which, in turn, are used to produce hundreds of other end-products. Most elhylene is produced by sleam cracking of ethane or propane. 

Ethylbenzene is transformed into (R)-p hen ethyl alcohol with an ee of 97% whereas propylbenzene yields the S-configured alcohol in 88% ee. The enantioselectivity remains high even with longer-chain substrates, for which the catalytic performance is rather inefficient [249].

Alkylation by zeolites made a major entry in the field of industrial catalysis through the highly acclaimed Mobil-Badger process for ethylbenzene (Csicsery, 1984, Hoelderich et al., 1988 Hoelderich and Van Bekkum, 1991) by replacing the toxic, eco-unfriendly, corrosive Friedel-Crafts reaction. A modified version developed by the National Chemical Laboratory (the Albene process), using a similar class of catalysts known as Encilites, is particularly suited to alkylation by ethyl alcohol of any concentration down to 30% (Bhowmik and Ratnasamy, 1991).
