Abstract
Toluene and toluene derivatives are dehydrocoupled to stilbene and stilbene derivatives in a vapor phase reaction in the presence of a metal oxide. The stilbene products are purified of by-product polar impurities. The purified stilbene can be catalytically reacted in the vapor phase with ethylene to produce styrene.
