Abstract

Biological agent defeat formulations containing an iodinated binder offer a unique solution for sterilization and neutralization of the surrounding environment in the form of iodine gas generation. This study characterized the thermal reactivity of an iodinated binder: hexamethylene diamine (HMD) trimer (C20H30N4O2I4) when combined with aluminum and iron oxide (Al + Fe2O3) thermite. Laser ignition studies were performed to evaluate ignition time and energy, as well as in-situ monitoring of the reaction using a high-speed camera. Thermal analysis of HMD showed four stages of exothermic decomposition plus generation of gas phase iodine species released upon decomposition. Thermal analysis of HMD + Al + Fe2O3 is consistent with laser ignition studies that showed HMD aids ignition and reaction of the ternary mixture. Overall, HMD contributed to heating and ignition as well as provided a source for iodine gas in multiple stages of the thermal reaction.
