ABSTRACT:
The production of solutions of hydrogen peroxide in phenol or its derivatives, e.g. hydrocarbyl substituted phenols, halo substituted phenols or phenol ethers, is carried out in a single step. Practically no loss of hydrogen peroxide occurs since a total distillation of hydrogen peroxide together with phenol or phenol derivative is avoided. Simultaneously the solutions obtained are practically free from water. The mixture of phenol or phenol derivative and aqueous hydrogen peroxide is treated with a material that boils below the boiling point of hydrogen peroxide, phenol or phenol derivative or forms an azeotrope with water that boils below the boiling point of hydrogen peroxide, phenol or phenol derivative and the water removed as an azeotrope. The solution of hydrogen peroxide in phenol or phenol derivative which remains behind is suitable for carrying out oxidation reactions and above all, also for hydroxylation reactions. The latter as especially advantageously carried out in the presence of sulfur-, selenium-, or tellurium oxide.
