摘要

Process for stabilizing an aqueous solution of hydrogen peroxide against the decomposition produced by contaminants, characterized in that it comprises incorporating in said aqueous hydrogen peroxide solution: (a) from 0.005 to 0.03% of a nitrile acid compound trimethylene phosphonic acid from the group consisting of nitrile trimethylene phosphonic acid and the ammonium and alkali metal salts thereof and (b) a tin compound soluble in aqueous hydrogen peroxide, the tin compound of which is present in an amount which gives from 0.001 to 0.015 % of tin in said solution.
