ABSTRACT:
An improved method for the acid-catalyzed rearrangement of a dialkylbenzene dihydroperoxide to a dihydric phenol which eliminates the formation of an emulsion during the subsequent separation and recovery of the dihydric phenol in a process which utilizes water, the method comprising the addition of the acid as a solution in a water soluble organic solvent, preferably a ketone, which is non-reactive with the acid.
