Abstract
Composition which was used as a white smoke grenade consists of Aluminium(Al), Hexachloroethane(HCE) and Zinc Oxide(ZnO), etc. there is a possibility of misfire due to long term storage and there are very few reports on the mechanism behind misfire. In this study, an experimental method known as accelerated degradation testing is used to investigate the chemical mechanism resulting in misfire. The mechanism of chemical change during long term storage was analyzed with XRD and FT-IR. Analysis results suggest that a part of HCE consisting of the white smoke grenade disappeared and the other part was combined into <TEX>$ZnCl_2$</TEX>, <TEX>$AlCl_3$</TEX>, as a recycled intermediate product under closed system.
