| Chemical Properties | Hexahydro-1,3,5-trinitro-S-triazine is a
white crystalline compound. | | Chemical Properties | 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. | | Uses | HMX has uses similar to RDX, that is, as a base charge for
detonators and as an ingredient of bursting-charge and plastic
explosives by the military. | | Uses | To implode fissionable material in
nuclear devices to achieve critical mass; as a
component of plastic-bonded explosives and
solid fuel rocket propellants and as burster
charges in military munitions. | | Uses | In solid propellants and explosives. | | Definition | ChEBI: A tetrazocane that is 1,3,5,7-tetrazocane in which the hydrogen atom attached to each of the nitrogens is replaced by a nitro group. | | General Description | 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. | | Air & Water Reactions | Insoluble in water. | | Reactivity Profile | HMX is a high explosive. May begin a vigorous reaction that culminates in a detonation if mixed with reducing agents, including hydrides, sulfides and nitrides. May explode in the presence of a base such as sodium hydroxide or potassium hydroxide even in the presence of water. Presence of metal oxides increases thermal sensitivity. Wetting reduces sensitivity toward detonation. | | Health Hazard | Fire may produce irritating, corrosive and/or toxic gases. | | Fire Hazard | MAY EXPLODE AND THROW FRAGMENTS 1600 meters (1 MILE) OR MORE IF FIRE REACHES CARGO. | | Safety Profile | A poison by ingestion
and intravenous routes. An explosive.
Decomposes violently at 279OC. When
heated to decomposition it emits toxicfumes of NOx. See also EXPLOSIVES,
HIGH. | | Potential Exposure | A potential danger to those involved
in the manufacture of this material and its handling in
munitions and solid-propellant manufacture. It is also used
as a rat poison; a powerful military explosive; a base
charge for detonators; and in plastic explosives. | | Shipping | UN0483 Cyclotrimethylenetrinitramine, desensi-

by mass, Hazard Class: 1D; Labels: 1D-Explosive (with a
mass explosion hazard); D-Substances or articles which
may mass detonate (with blast and/or fragment hazard)
when exposed to fire. | | Incompatibilities | Heat, physical damage, shock, and deto-
nators. Detonates on contact with mercury fulminate. Keep
away from other explosives, combustibles, oxidizers (such
as chlorates, nitrates, perchlorates, permanganates, perox-
ides; bromine, chlorine, and fluorine); reducing agents; and
aqueous alkaline solutions. | | Waste Disposal | Pour over soda ash, neutralize
and flush to sewer with water. Also HMX may be recov-
ered from solid propellant waste. |
