Abstract
Cumene and secondary butyl benzene are produced simultaneously in a distillation column reactor by feeding propylene, butylene and benzene to the reactor. Unreacted benzene is removed as overheads and cumene and secondary butyl benzene are removed as products. The catalysts used are acid cation exchange resins, zeolites, particularly beta zeolite.
