Isothermal decomposition of hydroxylamine and hydroxylamine nitrate in aqueous solutions in the temperature range 80–160 ◦C

---

Abstract.
Hydroxylamine (HA) and hydroxylamine nitrate (HAN) have been involved independently in several tragic
accidents, which incurred numerous fatalities and injuries. Following these incidents, adiabatic calorimetry
and computational chemistry research was conducted on those compounds, suggesting potential
reaction pathways of their decomposition, but the mechanism of their unstable behavior, still have not
been completely understood.
In the present work, isothermal decomposition tests were performed accompanied with HPLC, ion
chromatography and UV analyses in the temperature range 80–160 ◦C. Condition-dependent autocatalytic
decompositions were demonstrated for HA and HAN, and an intermediate formation has been observed
that is most likely responsible for their autocatalytic behavior. These findings corroborate previously
reported computational chemistry results.
