The cumene process (cumenephenol process, Hock process) is an industrial process for synthesizing phenol and acetone from benzene and propylene. Hydroquinone, also known as benzene1,4diol, is prepared by dialkylation of benzene with propene to give 1,4diisopropylbenzene.
· Cumene processes consist of two fundamental chemical reactions: cumene is oxidized with air to form cumene hydroperoxide, and cumene hydroperoxide is cleaved to yield phenol and acetone. In this process, approximately kg of acetone and kg of phenol are produced per kg of cumene feedstock. The overall yield for the cumene process is 96
