Tin (II) stabilizer for hydrogen peroxide

摘要

A method for stabilizing hydrogen peroxide and the stabilized composition are claimed employing as a stabilizer a tin (II) salt of an acid selected from the group hydrofluoric acid, C6 to C17 saturated monocarboxylic acids and C2 to C6 saturated polycarboxylic acids, preferably oxalic acid. The tin content of hydrogen peroxide prepared from a tin (II) oxalate stock solution can be reduced by filtration to less than 1 mg/l if the tin oxalate stock solution has been properly aged.
