Azidonitrate Ester

Azidonitrate ester is a kind of Uquid-iich nitrogen compounds, which have not only properties of nitrate ester, but also the energy of azides. They are regarded as high energy adhesion agents and plasticizers, optimized materials of future propellants and polymer-bonded explosives. They have wide application foreground. 

Diazidoneopentyl nitrate is pentaerylthritol diazido dinitrate. Its chemical code is PDADN. 

The oxygen balance —46.35 % (calculated according to the production CO2) The nitrogen content 40.57 % 

Physical properties wax-Uke white solid with low melting point melting point (32-34 °C) density (1.507 g/cm ) dissolved in chloroform not dissolved in water The mechanical sensitivity impact sensitivity (50 %) with falling height 15.4 m friction sensitivity 4 % (25 kg, swing angle 66°) 

Since America first reported the synthetic method of PDADN [36] in 1987, the five-step processes have been used until now. These five steps include chlorination of pentaerythritol, cyclization, azido reaction, nitrolysis, and nitrification. The writer first brominated, then azidized, and finally nitrificated pentaerythritol. The three-step process to produce PD AD A has fewer steps with high yield (up to 78.62 %). It is easier to be applied in industry.
