FIELD: chemistry.
SUBSTANCE: invention relates to a process for manufacturing a purified aqueous hydrogen peroxide solution. Provided is a process for manufacturing a purified aqueous hydrogen peroxide solution, in which a crude aqueous hydrogen peroxide solution is subjected to a washing operation with at least one organic solvent and wherein an organophosphorus chelating agent, that comprises an acid group and does not comprise sulfur, is added to the organic solvent. Processes for manufacturing propylene oxide are also described.
EFFECT: provided is a process for manufacturing hydrogen peroxide with a low concentration of easily precipitating metals.
