Description
Hexahydro-1,3,5-trinitro-S-triazine is a white crystalline compound. HMX (high-melting explosive) is a completely N-nitrated, eight-membered heterocyclic ring compound analogous to RDX. HMX has a molecular weight of 296.16 and a melting point of 204°C. Virtually none of the toxicity information on HMX was published, but it was reviewed by the EPA.
Characteristics

0.16
Cyclotetramethylene tetranitramine, [wet with >= 10% water] appears as a white crystalline solid. Melting point 281°C. Practically insoluble in water. Water slurry mitigates explosion hazard. Used in solid propellants and explosives. The primary hazard is the blast effect and not flying projectiles and fragments.
