Mannitol hexanitrate (also known as MHN, hexanitromannitol, nitromannite, nitromannitol, Nitranitol and Mannitrin) is an organic nitrated compound, a powerful explosive with the chemical formula C6H8N6O18.
Mannitol hexanitrate will detonate if exposed to strong heat or mechanical shock. Its decomposition releases
MHN is a powdery solid at standard conditions, with density of 1.73 g/cm3, insoluble in water, but soluble in alcohols and ether.
Mannitol hexanitrate is a secondary explosive, with a detonation velocity of 8260 m/s. Its sensitivity is high, particularly at high temperatures (>75 °C) where it is slightly more sensitive than nitroglycerin. MNH has an oxygen balance of +7.1%. Mannitol hexanitrate is classified as a class B explosive.
Mannitol hexanitrate is not available to the general public, and purchasing it requires a license.
- Make blasting caps
Mannitol hexanitrate is sensitive to strong shock and friction, as well as heating, and may explode under the right conditions. If consumed, it results in severe headaches, due to being a strong vasodilator, property seen in other nitrated organic compounds.
Mannitol hexanitrate should be used as quickly as possible and not stored.
Mannitol hexanitrate can be neutralized by safely burning it or detonating it in a remote or safe area.
A better and less dangerous method involves strongly diluting it in alcohol, then slowly add dropwise a base like sodium hydroxide to hydrolyze it to mannitol and sodium nitrate. This reaction is highly exothermic and must be done very carefully at low temperatures and at low concentrations.
