Process for producing cumene UOP LLC

In a typical commercial process for the production of cumene, liquid benzene and liquid propylene are charged into an alkylation zone containing one or more reactors containing an alkylation catalyst In order to minimize the production of polyalkylated products of benzene it has been the practice to maintain a molar excess of benzene throughout the reaction zone ranging from about 4:1 to

Cumene Wikipedia

The original route for manufacturing of cumene was by alkylation of benzene in the liquid phase using sulfuric acid as a catalyst, but because of the complicated neutralization and recycling steps required, together with corrosion problems, this process has been largely replaced As an alternative, solid phosphoric acid (SPA) supported on alumina was used as the catalyst Since the mid1990s
