2,2‐Dinitro‐1,3‐Bis‐Nitrooxy‐Propane (NPN): A New Energetic Plasticizer

Abstract

A new energetic plasticizer, 2,2‐dinitro‐1,3‐bis‐nitrooxy‐propane (NPN), has been characterized. Its high oxygen balance, +12.5%, and low glass transition temperature, −81.5 °C (midpoint), makes it very attractive as an energetic plasticizer in solid propellants. The ability of NPN to lower the glass transition temperature and viscosity of uncured PolyNIMMO has been studied and compared to other energetic plasticizers, such as BDNPA/F and butyl‐NENA. NPN has a similar plasticizing effect as butyl‐NENA, both on depressing the glass transition temperature and lowering the viscosity. To increase the poor thermal stability of NPN, several conventional nitrocellulose/nitroglycerine stabilizers were evaluated. Further work is however needed to find a more effective stabilizer.

A study on the aliphatic energetic plasticizers containing nitrate ester and nitramine

“…The influence of nitro group on the decomposition of nitrate ester was also observed in the study on the thermal stability of 2,2-dinitro-1,3-bis-nitroxy-propane (III) energetic plasticizer [13]. It was confirmed that this plasticizer could not be available in propellant formulation because it decomposed in 2 days at 65 8C.…”

Energetics of Propellants and Explosives

“…Extensive studies on the formation of energetic materials have been carried out to formulate high-energy propellants and explosives [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. Crystalline energeticmaterials are composed of carbon structures.…”

Computational studies on nitratoethylnitramine (NENA), its tautomers and charged forms

“…The introduction of bu-NENA based gun propellant formulations would allow a better and mechanically improved, energetically enhanced, and less sensitive gun propellant [10][11][12][13][14]. There are some studies concerning their synthesis [15][16][17] and their explosive properties as insensitive energetic explosives [18][19][20]. Since its synthesis, alkyl-NENA has been at the center of intense research.…”
