摘要:
It is the objective to provide a method of stabilizing hydroxylamine at a high temperature and a high concentration or in a case that metal impurities such as Fe got mixed therewith, and a stabilized hydroxylamine solution. A method for stabilizing hydroxylamine related to the present invention is characterized by adding ethylenediamine-N,N′-di(o-hydroxyphenylacetic acid) as a preservation stabilizer.
