Abstract
Process for manufacturing an aqueous hydrogen peroxide solution comprising the following steps: —hydrogenating a working solution which comprises an alkylanthraquinone and/or tetrahydroalkylanthraquinone and a mixture of a non-polar organic solvent and a polar organic solvent wherein the concentration of non-polar organic solvent in said mixture is equal to or higher than 30 wt %; —oxidizing the hydrogenated working solution to produce hydrogen peroxide; and—isolating the hydrogen peroxide, wherein the polar organic solvent is a substituted cyclohexane carbonitrile.
