4‐Amino‐1,2,4‐triazolium nitrate (4‐ATN) is an energetic and non‐sensitive ionic liquid, which was introduced as a good candidate in previous works for the replacement of 2,4,6‐trinitrotoluene (TNT) in melt‐cast explosives. Since previous studies used pure nitric acid for nitration of 4‐ATN, the effect of the use of low price industrial nitric acids (50 %, 70 % and 98 %) is investigated on the percent yields of 4‐ATN. The thermogravimetric and differential scanning calorimetry (TGA/DSC) are done on the synthesized 4‐ATN with impure nitric acid at a heating rate of 10 K·min–1 by the vacuum system. The obtained TGA/DSC curves confirm decomposition of 4‐ATN involving melting and dissociation. Derivative thermogravimetric (DTG) curves of 4‐ATN at various heating rates are applied to obtain activation energy of thermolysis by several model‐free techniques. The calculated activation energies are in the range 78.7–87.7 kJ·mol–1, which are about 10 kJ·mol–1 more than the reported activation energy of industrial TNT (purity 98.2 %), i.e. 66–70 kJ·mol–1. Assessments of detonation performance of 4‐ATN are also compared with TNT, which show higher detonation performance of 4‐ATN. Thus, 4‐ATN can be used with nitramine compounds as melt‐cast explosives with higher thermal stability and detonation performance than corresponding nitramine compound/TNT explosives.

Future propellants and explosive research focus on developing compositions with less vulnerability without compromising performance. This has provided impetus for research in the area of high energy materials and compounds free from pollution, for safe handling, high performance, reliability and reproducibility. The energetic oxidizers and energetic binders are being developed in this scenario for use in composite propellants and explosives. In a propellant, the binder holds together the matrix containing solid oxidizer particles and finely divided metal particles. It provides structural integrity and aid the combustion of the propellant. Any new development in this area wherein the binder can contribute to the energetic is of immense importance. This can be achieved by incorporation of energetic groups such as nitrato (−ONO2), azide (−N3) or flurodinitro CF(NO2)2 as side chain or on to the existing polymer backbone. Among these, nitrato functionalized energetic binders can find application in myriad areas like boosters, plastic bonded explosives, gas generators and pyrogen igniters. The present article is a concise review on various types of nitrato binders; their synthesis, properties and their propellant studies. Copyright © 2017 John Wiley & Sons, Ltd.

2,4-Dinitrophenoxy ethanol (DNE) can be considered as a suitable plasticizer for propellants based on cellulose acetate. It was synthesized in two forms, raw and pure products, which were analyzed by FTIR spectroscopy, 1 H-NMR and 13 C-NMR spectroscopy, elemental analysis, gas chromatography, mass spectrometry and high-performance liquid chromatography. Thermal stabilities of the products, impurities in the raw products and the effect of DNE on the thermal behavior of cellulose acetate were investigated using simultaneous thermogravimetry-differential scanning calorimetry. The results suggest that the raw product containing a small amount of impurity has better thermal stability than the pure product.
