摘要: Ammonium dinitramide (ADN) has attracted great interest as a potential oxidizer for next generation rocket propellants. It is halogen-free alternative to ammonium perchlorate, which currently in wide used solid propellant oxidizer. However, ADN synthesis, N-nitration necessary form the N-(NO2)2 group. Using reaction calorimeter, thermal behavior of nitration sulfamates (K, Na, and NH4) using mixture acids (HNO3/H2SO4 HNO3/AcOH) agent was examined. The heat decomposition potassium sulfamate at −10 °C greater than that 20 °C. decreased following order: K salt>Na salt>NH4 salt HNO3/H2SO4. dipole moments were calculated, results revealed electronic states nitrogen different. Thus, affect sulfamates. HNO3/AcOH larger
