It is produced by the reaction of benzene and propene, using an acid catalyst; this is an example of a Friedel-Crafts reaction: In one process, benzene and propene (3:1) are passed over an acid catalyst, usually a zeolite such as ZSM-5 at ca 600 K and under pressure ( ca 10 atm) in a fixed bed reactor .
