|Section2= |Section3= |Section6= }} Hexanitrostilbene (HNS), also called JD-X, is an organic compound with the formula ()2. It is a yellow-orange solid.〔Jacques Boileau, Claude Fauquignon, Bernard Hueber and Hans H. Meyer "Explosives" in ''Ullmann's Encyclopedia of Industrial Chemistry'', 2009, Wiley-VCH, Weinheim. 〕 It is used as a heat resistant high explosive. It is slightly soluble (0.1 - 5 g/100 mL) in butyrolactone, DMF, DMSO, and ''N''-methylpyrrolidone. ==Production and use== It is produced by oxidizing trinitrotoluene (TNT) with a solution of sodium 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.〔 Because of its insensitivity but high explosive properties, HNS is used in space missions. It was the main explosive fill in the seismic source generating mortar ammunition canisters used as part of the Apollo Lunar Active Seismic Experiments.〔(NASA reference publication )〕 Its heat of detonation is 4 kJ/g.〔(Hexanitrostilbene and Its Properties )〕 It was developed at the U.S. Naval Ordnance Laboratory in the 1960s and has been improved on since then.〔Peter Golding, Asoka M.
