Abstract: The oxidation step in the anthraquinones process for producing hydrogen peroxide is carried out in a plurality of stages in an apparatus arranged for separating gas and liquid phases. The hydroquinone containing working solution is conducted in each stage in parallel flow from bottom to top with one oxygen containing gas. The stage with the highest hydroquinone concentration in the working solution is led to the gas mixture most depleted in oxygen and the fresh gas mixture is introduced into the stage which contains the working solution poorest in hydroquinone.
