Abstract
Process for splitting primary alkylaromatic hydroperoxides to yield phenolic products is described which consists of reacting the hydroperoxide with a catalytic amount of a compound with an acid reaction, in an organic solvent medium, the characteristic feature being that the splitting medium is a mixture consisting of: PA1 A. at least one solvent chosen from the group of aprotic polar solvents formed by polymethylene-sulphones, alkylene glycol carbonates which contain 2 to 4 carbon atoms (in the alkylene portion) and aliphatic or aromatic nitriles, and PA1 B. at least one hydroxylic solvent taken from the group formed by aliphatic alcohols containing 1 to 3 carbon atoms and alkylene glycols containing up to 4 carbon atoms.
