Cumene (98-82-8) is manufactured by reacting benzene with propylene over a catalyst such as a phosphoric acid derivative at 175 to 250 °C and 400 to 600 psi. A refinery cut of mixed propylene-propane is frequently used instead of the more expensive pure propylene. Benzene is provided in substantial excess to avoid polyalkylation.
