Abstract
The present invention relates to a process for the preparation of high-purity, stabilized hydroxylamine solutions in which an aqueous hydroxylamine starting solution is treated with an anion exchanger which has been pre-loaded with a hydroxylamine stabilizer in order to remove anions.
Claims7
A process for the preparation of high-purity, stabilized hydroxylamine solutions by treating an aqueous, anion-containing hydroxylamine starting solution with an anion exchanger, which comprises using an anion exchanger which has been pre-loaded with a hydroxylamine stabilizer.
A process for reducing the anion concentrations in aqueous hydroxylamine solutions, in which an aqueous hydroxylamine solution is treated with an anion exchanger which has been pre-loaded with a hydroxylamine stabilizer.
