A working solution for producing hydrogen peroxide, containing an alkylanthraguinone working compound dissolved in a solvent, is regenerated by contacting the working solution with a catalyst containing from 5% to 100% boehmite at a temperature of 25° C. to 150° C. At least a portion of the tetrahydro-alkylanthraquinone epoxide present in the working solution is converted to working compound to maintain the composition of the working solution within specified limits.
