Styrene can be synthesized from benzene in a relatively simple two-step mechanism.
- 1. Friedel-Crafts alkylation
An ethyl group (R) is electrophilically added to the benzene ring from chloroethane with the help of an iron chloride catalyst. The product is ethylbenzene.
- 2. Catalytic dehydrogenation of ethylbenzene in the gas phase in the presence of hot steam over a heterogenous iron(III) oxide catalyst bed. The product is styrene.
