  • Stabilizers for hydroxylammonium nitrate, hydroxylammonium nitrate derivatives, hydroxylamine and compositions containing the same
    Patent number: 6179937
    Abstract: The stability of HAN, HAN derivatives or hydroxylamine, and compositions comprising these is considerably enhanced by employing a stabilizing effective amount of a stabilizer selected from (a) a pyridine or pyridone salt, or an acid thereof; (b) a diphosphonate or methylenephosphonate salt, or an acid thereof; or (c) a mixture of two or more stabilizers, wherein at least one is selected from (a) and at least one is selected from (b). Stabilized HAN, HAN derivatives, or hydroxylamine or compositions comprising HAN, an HAN derivative or hydroxylamine, along with a process for providing these stabilized compositions is described. A stabilizer mixture having enhanced, synergistic stabilizing properties is described as well.
