ABSTRACT:
A process is provided to regenerate and purify a working solution for the manufacture of hydrogen peroxide by the reduction and oxidation of a solution of alkylated anthraquinones and derivatives. The regeneration and purification is effected by removing inerts by contacting the working solution and an noncyclic hydrocarbon to form a liquid first phase and a second phase, separating the two phases and recovering both the noncyclic hydrocarbon and the purified working solution by distillation.
