1,3-diazido-2-nitryloxypropane(DANG),also know as azido-substituted nitrglycerin (NG),was synthesized using 1,3-dichloro-2-propanol as starting material via azidation and nitration. The structures of both DANG and its intermediate 1,3-diazido-2-propanol (DAHP) were identified by IR,¹HNMR and elemental analysis. HPLC results show that the purity is 98.0% for DAHP and 96.0% for DANG respectively. In addition,some important properties of DANG,including solidafication point,thermal stability,friction sensitivity,and impact sensitivity were all determined,and it has been proved that DANG remains liquid state at -15 ℃.
