METHOD FOR PRODUCTION OF HYDROGEN PEROXIDE Russian patent published in 1996 - IPC

FIELD: production of hydrogen peroxide. SUBSTANCE: method for production of hydrogen peroxide includes preparation of working solution which contains 85 kg/cu.m of 2-ethylanthraquinone and 30 kg/cu.m of tetrahydroanthraquinone dissolved in mixture of octanole-2 and preudocumene in volumetric ratio of 1:1; hydration at 50 C in the presence of nickel catalyst; oxidation in countercurrent apparatus with air enriched with oxygen up to its content of 50% at pressure of 1.5 kgf/sq.cm and temperature of 48 C, flow rate of hydrated solution of 0.012-0.02 cu.m/sq.m.s, and air of 0.3-0.6 cu. m/sq. m. s. Hydrogen peroxide is extracted in extraction column. Oxidation degree is 98.7-99.8%, oxidation time 17.7-47.2 min, specific efficiency in terms of 100% hydrogen peroxide is 30.6-52 kg/cu.m.h. EFFECT: higher efficiency. 1 tbl
