ABSTRACT:
A process is provided to remove inert contaminants from a working compound employed for the manufacture of hydrogen peroxide by the reduction and oxidation of a solution of alkylated anthraquinones and derivatives. The contaminants are removed by the process of contacting the working compound, a solvent, and carbon dioxide to form a first portion and a residue portion, separating the two portions and recovering the purified working solution from the first portion.
