Studies on Triple Base Gun Propellant Based on Two Energetic Azido Esters

Link between Density and Molecular Structures of Energetic Azido Compounds as Green Plasticizers

“…Organic azides are energetic molecules that are widely used as ingredients of propellants, explosives and pyrotechnics. It is shown that introduction of an azido group into an organic compound enhances its energy content approximately 355 kJ·mol –1 …”

Studies on the high-energy gun propellant formulations based on 1,5-diazido-3-nitrazapentane

“…However, the main disadvantages of these plasticizers are low thermal stability due to the presence of secondary hydroxy groups (NG, BTTN), low energy (BDNPF/A, METN, DEGN), and high vapor pressure (DEGN, NG) [4]. In view of this, novel energetic plasticizers such as glycidyl azide polymer (GAP) [5,6], N-n Butyl-N-(2-Nitroxyethyl) nitramine (Bu-NENA) [7], azido ester plasticizers such as tris (azido acetoxy methyl) propane (TAAMP) and bis (azido acetoxy) bis (azido methyl) propane (BABAMP) [8] have been reported to be used for the replacement of organic phthalates so as to increase the energy of the propellant. Flanagan et al have suggested the use of 1,5-diazido-3-nitrazapentane (DANPE) as energetic plasticizer for gun propellant formulations in a patent [9].…”

Synthesis and Properties of 3‐Azido‐2,2‐bis(azidomethyl)propyl 2‐Azidoacetate: A Potential Azido Ester Plasticizer

“…The function of a plasticizer is to improve safety and augment mechanical properties . Ideal plasticizers should be highly compatible with polymers, stable at high and low temperatures, sufficiently lubricating over a wide temperature range, insensitive to ultraviolet radiation, leaching and migration resistant, inexpensive and should fulfill health and safety regulations …”

“…[1][2] Ideal plasticizers should be highly compatible with polymers, stable at high and low temperatures, sufficiently lubricating over a wide temperature range, insensitive to ultraviolet radiation, leaching and migration resistant, inexpensive and should fulfill health and safety regulations. [3][4] Inert (non-energetic) and energetic plasticizers are all used in propellant formulation. [5] However, inert plasticizers have the disadvantage of reducing the energy output of the system.…”
