Abstract

A process for producing stilbene and stilbene derivatives free of polar impurities, from toluene and toluene derivatives as starting hydrocarbons, comprising: (a) effecting dehydrogenating coupling of toluene and toluene derivatives in the vapor phase in the presence of a solid metal oxide at a temperature in the range of from about 500ºC to about 650ºC, (b) separating the dehydrogenating coupling effluent to give a stilbene fraction, (c) treating said stilbene fraction to remove polar impurities, and (d) recovering said stilbene fraction substantially free of polar impurities.
