Abstract

PURPOSE: To improve the selectivity of an alkyl aromatic compound as a raw material having a bulky alkyl group, by adding a mercaptan successively and increasing its recovery amount, in obtaining a phenol in one stage through oxidation of an alkyl aromatic compound in the liquid phase.
CONSTITUTION: An alkyl aromatic compound, e.g. an aromatic hydrocarbon containing a secondary alkyl group, such as cumene or cymene, is oxidized with molecular oxygen in the liquid phase, in the presence of a mercaptan having an acid dissociation constant less than 7.8, to prepare a phenol. A mercaptan is added continuously or intermittently with increasing conversion of the alkyl aromatic compound. An organic carboxylic or sulfonic acid may be preferred as a solvent, and the initial existence of a phenol improves the reaction rate, reduces the reaction time, and in addition, enables the continuous oxidation.
