Abstract
Improved recycle processes for preparing hydrogen peroxide to hydrogenating alkylanthraquinone in a solvent to form hydrogenated alkylanthraquinone, treating the resulting liquid with an oxygen-containing gas to form hydrogen peroxide and regenerate the quinone, extracting the hydrogen peroxide with water, and recycling the quinone, wherein the quinones are 2-ethylanthraquinone (EAQ) and 2-ethyl-5,6,7,8-tetrahydroanthraquinone (H.sub.4 EAQ) and losses of quinone are made up exclusively with H.sub.4 EAQ, the solvent being methylcyclohexyl acetate and a nine carbon-atom alkylbenzene, these processes providing reduced losses of the active intermediate and improved operation of the hydrogen peroxide production unit.
