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.
