Abstract

PURPOSE: To prepare the titled compound free from isomers, by oxidizing a methyl- substituted aromatic compound in the presence of an easily and economically available cumene hydroperoxide concentrate, and heat-decomposing the resulting product obtained in high yield without by-products, without separating the product from the reaction mixture.
CONSTITUTION: A primary hydroperoxide is prepared by the liquid phase oxidation of the corresponding methyl-substituted aromatic compound such as toluene, o-, m-, or p-xylene, α-methylnaphthalene, etc., with an O2-containing gas in the presence of cumene hydroperoxide concentrate obtained by concentrating the oxidation reaction mixture of cumene, pref. at 90W140°C and 5W20kg/cm2G, thereby oxidizing one of the methyl groups of the methyl-substituted aromatic compound. The reaction mixture obtained by the above oxidation reaction is concentrated to obtain a liquid containing cumene hydroperoxide and the above primary hydroperoxide, and the concentrate is decomposed in the presence of an acidic catalyst to obtain the corresponding phenols.
