Transcribed image text: The cumene process is used to convert benzene and propene in the presence of oxygen to phenol and acetone via the reaction CH, +C,H, +2, C,H,OH +C,H,O This reaction is carried out with excess benzene and excess oxygen to ensure that no side reactions occur. A 1.21 ratio of benzene to propene is fed to a reactor in the presence of 30.0% excess air (N, and O2).
