3,3'-二硝氨基-4,4'-氧化偶氮呋咱羟胺盐的热行为和热安全性研究
Thermal Behavior and Safety of Dihydroxylammonium 3,3'-dinitroamino-4,4'-azoxyfurazanate
摘要
Abstract
The thermal decomposition behaviors of dihydroxylammonium 3,3'-dinitroamino-4,4'-azoxyfurazanate (HNAF) were studied by using a C-500 type Calvet microcalorimeter at five different heating rates.The kinetic parameters of exothermic decomposition reaction were calculated by the Kissinger and Ozawa methods and then thermodynamic parameters were also determined.The specific heat capacity of dihydroxylammonium 3,3'-dinitroamino-4,4'-azoxyfurazanate was measured with a Micro-DSC Ⅲ calorimeter.The results show that the apparent activation energy(E),pre-exponential constant(A),the entropy of activation(△S≠),the enthalpy of activation(△H≠) and the Gibbs free energy of activation(△G≠) are 205.26 kJ/mol,1020.32s-1,140.76J/(mol · K),201.56 kJ/mol and 200.39 kJ/mol,respectively.The specific heat capacity equation and the molar specific heat capacity were determined as Cp =-1.560 + 0.016 T-2.263 × 10-5 T2 (J / (g · K)) and 446.028 J /(mol·K),respectively.The self-accelerating decomposition temperature,adiabatic decomposition temperature rise,critical temperature of thermal explosion and adiabatic time-to-explosion are 444.44 K,2 382.89 K,452.86 K,12.46 s and 12.54 s,respectively.关键词
