Thermal Properties of 1-Amino-1-hydrazino-2,2-dinitroethylene Cesium Salt

Abstract

A new high-energy organic cesium salt, 1-amino-1-hydrazino-2,2-dinitroethylene cesium salt [Cs(AHDNE)], was synthesized by reacting of 1-amino-1-hydrazino-2,2-dinitroethylene (AHDNE) and cesium chloride in alkali methanol aqueous solution. The thermal behavior and nonisothermal decomposition kinetics of Cs(AHDNE) were studied. The kinetic equation obtained is . The self-accelerating decomposition temperature (TSADT) and critical temperature of thermal explosion (Tb) of Cs(AHDNE) are 152.9 and 163.5°C, respectively. The specific heat capacity of Cs(AHDNE) was determined with a micro-differential scanning calorimetry (DSC) method, and the molar heat capacity was 223.62 J mol−1 K−1 at 298.15 K. The adiabatic time to explosion of Cs(AHDNE) was 93.5 s. Cs(AHDNE) has higher thermal stability than AHDNE. Cs(AHDNE) is sensitive to impact and friction.
