摘要： The specification provides a method of producing cumene hydroperoxide by continuous aqueous-emulsion oxidation at a high temperature and pressure in a cascade of reactors, wherein the process is conducted in the presence of a mixture of an aqueous solution of an ammonium salt with a concentration of 0.001-0.5 mass % and an aqueous solution of ammonia with a concentration of 0.001-0.5 mass %, which mixture is fed into each oxidation reactor in an ammonia:ammonium salt mass ratio of 1:100 to 100:1.

摘要： The goal of this invention is to produce phenol of high purity by conversion of impurities that are present in the starting phenol, which is produced by the decomposition of cumyl hydroperoxide. The indicated goal is achieved by purifying the phenol containing admixtures of aliphatic and aromatic carbonyl compounds with an aluminum zirconium catalyst.
