In order to make unexploded ordnance lose explosive ability,the chemical failure of HMX that is usually used as detonating explosive and booster was studied so as to find the corresponding chemical reagents,which can decompose HMX into compounds without explosive properties.For this purpose,several decomposition experiments between HMX and NaOH,HMX and thick H2 SO,HMX and mixed acid under different temperature conditions were carried out.According to the experimental results,it can be concluded that HMX can be decomposed by a mixture of concentrated nitric acid and concentrated nitric acid with the volume ratio of 3∶1.When its decomposed level reaches 60%,HMX will not be detonated,therefore the failure purpose is achieved.
