Reaction Tendencies:
HMX, for a high explosive, is actually pretty stable. The reason the military uses HMX so widely is because of this stability: in most conditions HMX will only explode if you want it to. HMX is not known to react violently with any other chemicals and usually won't even react at all. Although HMX is stable when mixed with other chemicals and when heated, it will still explode under heavy shock or friction and must be desensitized in one way or another during transport. However, more stable does not mean less powerful as HMX is currently the most powerful high explosive used by the military.
HMX will not dissolve in water, but will dissolve in several other chemicals, such as acetone.
