Alpha-Methylstyrene → Cumene

Participants

Reaction Steps

However, the typical process for industrial production of α-methylstyrene is the cumene-phenol production process. This cumene-phenol production process contains a step in which cumene hydroperoxide obtained by oxidation of raw material cumene is concentrated to 80 to 85% followed by acid decomposition to phenol and acetone and neutralization/washing. The resulting crude phenol contains such substances as acetone, water, cumene, α-methylstyrene and phenol, and purified phenol is produced from this crude phenol by distillation, while at the same time, acetone and α-methylstyrene are respectively separated and recovered (see, for example, Patent Documents 3 and 4).
