Abstract

An aromatically substituted carbinol of the general formula Ar(R)2C.OH, in which Ar is an aromatic hydrocarbon radical and R is an alkyl radical, is produced by decomposing the corresponding hydroperoxide or its alkali or alkaline earth metal salt in an alkaline medium at an elevated temperature. The preferred temperature for carrying out the process is between 50 DEG and 150 DEG C. It is advantageous to effect the decomposition in the presence of the corresponding hydrocarbon since part of the hydrocarbon is then turned into the carbinol during the process. A solution of the hydroperoxide in the corresponding hydrocarbon, obtained by partial oxidation of the hydrocarbon, or the pure hydroperoxide may be flowed into a heated solution or emulsion of hydrocarbon and aqueous alkali. When an alkali or alkaline earth metal salt of a hydroperoxide is decomposed, the alkaline medium is provided instantaneously by decomposition products. In the examples cumyl hydroperoxide and sodium cumyl hydroperoxide are decomposed to give dimethylphenyl carbinol with small amounts of acetophenone and benzoic acid; and p-cymylhydroperoxide is decomposed to give dimethyl-p-tolyl carbinol with some p-methyl acetophenone and p-toluic acid. The cumyl hydroperoxide used as starting material may be made by mixing cumene with oxygen and heating the mixture in the presence of copper phthalocyamine.
