Mannitol hexanitrate or nitromannitol is a chemical compound from the group of nitric acid esters and a rarely used explosive. It can be used both as an initial explosive and as a main charge. Due to its poor stability , it is not used in Europe as it can be replaced by other more stable explosives. Only in the USA has it achieved a certain importance as a detonator filling. It is stabilized with ammonium carbonate and must be absolutely acid-free, otherwise it can detonate spontaneously.
Extraction and presentation
Mannitol hexanitrate forms colorless crystalline needles that melt at 112 to 113 ° C. The standard enthalpy of formation Δ f H 0 solid is −708.8 kJ mol −1 , the combustion enthalpy Δ c H 0 solid is −2936 kJ mol −1 .
