Synthesis and sensitivity of hexanitrohexaaza-isowurtzitane (HNIW)

Hexanitrohexaaza-isowurtzitane (AC-HNIW) was synthesized by using a precurs or invented by Asahi. The purity, which was measured by high performance li quid chromatography (HPLC), was determined to be 99.2%. From the results, i t is expected that the propellants or explosives composed of AC-HNIW indica ted higher performance in specific impulse, ballistics and detonation veloc ity. The structure of AC-HNIW was identified by IR and NMR. The results ind icated that AC-HNIW had the same structure as CL-20 which was produced by T hiokol corporation. The sensitivity and thermal decomposition properties of AC-HNIW were also measured in order to elucidate HNIW performance. The res ults were compared with CL-20. The sensitivity of AC-HNIW was determined to be the same as CL-20.
