Nitromethane explosive properties
Nitromethane is a nitrated hydrocarbon with the blueprint CH3NO2. It is a aqueous at allowance temperature.
Nitromethane was not accepted to be a top atomic until a railroad tanker car loaded with it exploded on June 1, 1958.After abundant testing it was accomplished that nitromethane was a added active top atomic than TNT, although TNT has a college acceleration of blast and brisance. Both of these explosives are oxygen poor and some allowances are acquired from bond with an oxidizer, such as ammonium nitrate. Pure nitromethane is an aloof atomic with a VoD of about 6,400 m/s (21,000 ft/s), but even so inhibitors may be acclimated to abate the hazards. The catchbasin car access was speculated to be due to adiabatic compression, a hazard accepted to all aqueous explosives. This is if baby entrained air bubbles abbreviate and superheat with accelerated rises in pressure. It was anticipation that an abettor rapidly airtight shut a valve creating a "hammer-lock" burden surge.
Nitromethane can aswell be alloyed with ammonium nitrate, which is acclimated as an oxidizer, to anatomy an atomic admixture accepted as ANNM. One clear archetype of this was the use of nitromethane and ammonium nitrate in the Oklahoma City bombing.
