Abstract:
1. A process for producing phenol, the process comprising: (a) contacting benzene with a C (b) oxidizing at least part of the cumene produced in (a) in the presence of an oxidizing gas to produce an oxidation effluent comprising cumene hydroperoxide and unreacted cumene and a spent oxidizing gas; (c) treating at least part of the unreacted cumene from the oxidation effluent to remove nitrogenous impurities therefrom and produce a purified cumene stream; (d) recycling the purified cumene stream to the oxidizing (b); (e) cleaving at least part of the cumene hydroperoxide from the oxidation effluent to produce a cleavage effluent comprising phenol and acetone; (f) recovering phenol from the cleavage effluent; (g) hydrogenating at least part of the acetone from the cleavage effluent to produce isopropanol; and (h) recycling at least part of the isopropanol from (g) to the contacting (a).
