WATER HYDROGEN PEROXIDE SOLUTION, METHOD OF ITS OBTAINING AND ITS APPLICATION Russian patent published in 2012 - IPC C01B15/01 C01B15/23 C07D301/12 

FIELD: chemistry.

SUBSTANCE: invention relates to water hydrogen peroxide solution, to method of obtaining water hydrogen peroxide solution and application of said solution in the process of olefin epoxidation. Water hydrogen peroxide solution with concentration of peroxide solution [H₂O₂], expressed in % by solution weight, has apparent pH value from pH_min to pH_max, so that pH_min=3.45-0.0377×[H₂O₂], pH_max=3.76-0.0379×[H₂O₂], where water hydrogen peroxide solution has concentration of peroxide solution [H₂O₂], expressed in % by solution weight equal more than 5% and less than 80%. Method of obtaining includes hydrogenation of water solution, which contains, at least, one organic solvent and, at least, one alkylane trachinone compound, b) oxidation of hydrogenated working solution with obtaining hydrogen peroxide, c) extraction of hydrogen peroxide with water medium, d) optionally, addition of stabiliser to extracted water hydrogen peroxide solution, e) concentration of water hydrogen peroxide solution to required concentration of hydrogen peroxide, and f) optionally, regulation of pH of water hydrogen peroxide solution.

EFFECT: increase of degree of hydrogen peroxide transformation in the process of olefin epoxidation.
