Abstract

PURPOSE: To prepare phenols in high yield, by the cleavage reaction of a mixture of an aromatic tert-hydroxyperoxide and an aromatic prim-hydroxyperoxide in a solvent composed of an aliphatic ketone and an aliphatic alcohol in the presence of an acid.
CONSTITUTION: Phenols (e.g. p-cresol, p-isopropylphenol, etc.) are prepared by the cleavage reaction of an aromatic tertiary hydroperoxide (e.g. p-methylcumene hydroperoxide) and an aromatic primary hydroperoxide (e.g. p-isopropylbenzyl hydroperoxide) in the presence of an acid (e.g. sulfuric acid). The reaction is carried out in a mixed solvent composed of (A) 60W99pts.wt., pref. 70W95pts.wt. of an aliphatic ketone (e.g. acetone) and (B) 40W1pts.wt., pref. 30W5pts.wt. of an aliphatic alcohol (e.g. methanol).
EFFECT: Methylbenzenes which are difficult to be oxidized to the corresponding hydroperoxides, can be converted to the hydroperoxides by oxidizing in the presence of cumene or cumene hydroperoxide.
