    摘要： In a process for producing phenol, benzene is contacted with a C3 alkylating agent comprising isopropanol under alkylation conditions such that at least part of the isopropanol reacts with the benzene to produce cumene. At least part of the resultant cumene is then oxidized in the presence of an oxidizing gas to produce an oxidation effluent comprising cumene hydroperoxide, unreacted cumene and a spent oxidizing gas. The unreacted cumene is separated from the oxidation effluent and is treated to remove nitrogenous impurities therefrom and produce a purified cumene stream, which is recycled to the oxidization step. At least part of the cumene hydroperoxide from the oxidation effluent is cleaved to produce a cleavage effluent comprising phenol and acetone. The phenol is recovered phenol from the cleavage effluent, whereas at least part of the acetone from the cleavage effluent is hydrogenated to produce isopropanol for recycle to the alkylation step.

    摘要： In a process for oxidizing an alkylaromatic compound to the corresponding hydroperoxide, a feed comprising an alkylaromatic compound is contacted with an oxygen-containing gas in the presence of a catalyst comprising a cyclic imide. The contacting is conducted at a temperature of about 90° C. to about 150° C., with the cyclic imide being present in an amount between about 0.05 wt % and about 5 wt % of the alkylaromatic compound in the feed and the catalyst being substantially free of alkali metal compounds. The contacting oxidizes at least part of the alkylaromatic compound in said feed to the corresponding hydroperoxide.

    摘要： A method for producing phenol and acetone in a multi-stage process at an elevated temperature from a cumene hydroperoxide mixture comprising cumene, comprises the steps of:a) distilling an amount of cumene from the cumene hydroperoxide mixture until the cumene mass % is 0 to 7 mass % relative to the total mass of the cumene hydroperoxide mixture,b) reacting the cumene hydroperoxide mixture with an acid catalyst form to a second mixture comprising phenol, acetone and dicumyl peroxide in a first stage, andc) decomposing the second mixture in a second stage to produce phenol and acetone,wherein an amount of phenol approximately equal to the amount of distilled from the cumene hydroperoxide mixture is added to the cumene hydroperoxide mixture before the reacting step b). The amount of hydroxyacetone is reduced, thereby, improving the quality of commercial-grade phenol and the products made from the phenol.
