Benzene → HCID 14423575, compound

Participants

Reaction Steps

When benzene is alkylated with ethylene in the presence of an alkylation catalyst, a reaction product containing unreacted benzene, alkylbenzenes, polyalkylbenzenes and heavier products is obtained. The above 1-(3-ethylphenyl)-1-phenylethane of the formula (V) is recovered as a fraction mainly containing components having a boiling point of 285° to 290° C. (atmospheric pressure basis) by distillation such as reduced-pressure distillation. The fraction is then dehydrogenated in the presence of a dehydrogenation catalyst, and if necessary, it is followed by distillation, to obtain 1-(3-vinylphenyl)-1-phenylethylene of the formula (III).
