Hexanitrostilbene (HNS), also calledJD-X, is anorganic compound with the formula [(O2N)3C6H2CH]2. It is a yellow-orange solid.[1] It is used as a heat-resistanthigh explosive. It is slightly soluble (0.1 - 5 g/100 mL) inbutyrolactone,DMF,DMSO, andN-methylpyrrolidone.
It is produced by oxidizingtrinitrotoluene (TNT) with a solution ofsodium hypochlorite. HNS boasts a higher insensitivity to heat than TNT, and like TNT it is insensitive to impact. When casting TNT, HNS is added at 0.5% to form erratic micro-crystals within the TNT, which prevent cracking.[1] Because of its insensitivity but high explosive properties, HNS is used in space missions. It was the main explosive fill in theseismic source generatingmortar ammunition canisters used as part of theApollo Lunar Active Seismic Experiments.[2]
Its heat of detonation is 4 kJ/g.[3]
It was developed byKathryn Grove Shipp at the U.S.Naval Ordnance Laboratory in the 1960s and has been improved on since then.[4]
