Cyclic prepn of hydrogen peroxide - by hydrogenation of 2-alkylte trahydroanthraquinone followed by oxidation

摘要

Cyclic process for the prodn. of H2O2 consists of hydrogenation of 2-alkyltetrahydroanthraquinone (ATHT) dissolved in water-immiscible org. solvent, and oxidn. of the 2-alkyltetrahydroanthrahydroquinone, using a gas, contg. oxygen, to H2O2 and the 2-alkyltetrahydroanthraquinone , which is recycled, after sepn. of the H2O2. For the ATHT is used a mixture of 2-tetra-amyltetrahydroanthraquinone, and 2-sec.iso-amyltetrahydroanthraquinone.
