Abstract

In a cyclic process for the production of hydrogen peroxide involving successive reduction and oxidation of an anthraquinone solution and aqueous extraction of hydrogen peroxide, the solution, or degraded solids separated from the solution, have their peroxide-producing capacity regenerated by treating with O2, an O2-containing gas, H2O2, or other oxidizing agent in the presence of a water-soluble base. The treatment is carried out after extraction, but before reduction, and the bases may be used in alcoholic solution. A portion of the solution may be withdrawn from the cycle for treatment and returned after water washing. Exemplified bases are aqueous NaOH and KOH, alcoholic KOH, sodium ethoxide, ammonia, Ca(OH)2, pyridine, and trieththylamine. This oxidation treatment may be combined with the known regeneration treatment of contacting with porous artificial alumino silicates, e.g. sodium aluminium silicate at 90 DEG C. This contact may be before the oxidation treatment, or on a separate portion of solution simultaneously. Specifications 465,070 and 838,939 are referred to.
