Abstract:
The behavior of a droplet of $\beta$-azidoethanol, a liquid explosive, in heated air was studied. It was shown that droplet ignition is a gas-phase process limited by heat release due to the vapor-phase oxidation of azidoethanol. An increase in the ambient temperature with distance from the ignition limit eads to enhancement of the role of the thermal decomposition of azidoethanol molecules. In the range of ambient temperatures of 560–620 K, the droplet ignition is determined by the kinetics of the parallel reactions – the gas-phase oxidation and thermal decomposition of azidoethanol.
Keywords:ignition, chemical reaction kinetics, ignition delay, activation energy, explosive, azidoethanol.
