Abstract

Provided are a method for stabilizing hydroxylamine at high temperatures and high concentration and/or in the presence of metal impurities such as Fe, and a stabilized hydroxylamine solution. The method for stabilizing hydroxylamine includes adding 3,4-dihydroxybenzoic acid as storage stabilizer, and optionally an antioxidant.
