Abstract

PURPOSE: To obtain phenol in high yield without using a corrosion-resistant decomposition reactor, by decomposing 1-phenylethyl hydroperoxide in the presence of a novel catalyst of a dialkylthiuram disulfied.
CONSTITUTION: 1-Phenylethyl hydroperoxide and a dialkylthiuram disulfide catalyst are dissolved in a suitable solvent, and decomposed at 50W200°C, preferably 80W120°C, to give phenol. Dimethylthiuram disulfide, diethylthiuram disulfide, etc. may be cited as the catalyst, and the amount is 0.00001W0.1 mole, preferably 0.0001W0.01 mole per mole of the raw material.
EFFECT: Simple separation procedures.
