Abstract
An anthraquinone autoxidation process has been developed for producing hydrogen peroxide employing N-substituted-2-pyrrolidones as solvents for the anthrahydroquinone formed in the reduction step. These new solvents have improved solubility characteristics over prior solvents. Particular N-substitutents are alkyl and alkaryl groups containing 6 to 12 carbon atoms.
Claims14
An improved process for producing hydrogen peroxide by the alternate reduction and oxidation of a substituted anthraquinone and its tetrahydro derivative as the working compound, dissolved in a solvent to constitute a liquid working solution wherein the improvement resides in using a solvent comprising an N-substituted-2-pyrrolidone wherein the substituted moiety is a hydrocarbon containing 6 to 12 carbon atoms.
