Synthesis and properties of HNIW

ε-HNIW samples were prepared by nitrolysis of two chemicals tetraacetyldiformylhexazaisowurzetane (TADFIW) and tetraacetyldibenzylhexazaisowurzetane (TADWBIW) respectively. Thermal decomposition parameters and impact sensitivity (H₅₀) of the two kinds of HNIW samples were determined and SEM photographs were given. The test results show that thermal decomposition parameters and impact sensitivity (H₅₀) of the two samples are almost same, which indicate that these samples have the same chemico-physical properties and the different impurities contained in ε-HNIW samples mentioned above do not affect chemico-physical properties of these samples greatly.
