Hydroxylamine nitrate (HAN) is an important member of the hydroxylamine family and it is a liquid propellant when combined with alkylammonium nitrate fuel in an aqueous solution. Low concentrations of HAN are used primarily in the nuclear industry as a reductant in nuclear material processing and for decontamination of equipment. Also, HAN has been involved in several incidents because of its instability and autocatalytic decomposition behavior. This paper presents calorimetric measurement for the thermal decomposition of 24 mass% HAN/water. Gas phase enthalpy of formation of HAN is calculated using both semi-empirical methods with MOPAC and high-level quantum chemical methods of Gaussian 03. CHETAH is used to estimate the energy release potential of HAN. A Reactive System Screening Tool (RSST) and an Automatic Pressure Tracking Adiabatic Calorimeter (APTAC) are used to characterize thermal decomposition of HAN and to provide guidance about safe conditions for handling and storing of HAN.
硝酸羟胺（HAN）是羟胺家族的重要成员，当它与硝酸烷基铵燃料在水溶液中混合时，是一种液体推进剂。低浓度的HAN主要用于核工业，作为核材料加工中的还原剂以及设备去污。此外，由于HAN的不稳定性和自催化分解行为，它还涉及多起事故。本文介绍了对24质量% HAN/水热分解的量热测量。使用MOPAC的半经验方法和高斯03的高水平量子化学方法计算了HAN的气相生成焓。CHETAH用于估计HAN的能量释放潜力。使用反应系统筛选工具（RSST）和自动压力跟踪绝热量热仪（APTAC）来表征HAN的热分解，并为HAN的处理和储存提供安全条件方面的指导。
