Synthesis and Crystallization of Hydrazinium Nitroformate.
The invention relates to crystalline hydrazinium nitroformate having a length to diameter ratio of at most 2.5 and a sensitivity to friction and shock not below 20 N and 2 J, respectively, as well as to a method for the preparation thereof.
Synthesis of azido polymers as potential energetic propellant binders 203. (i) catalysts, which enhance the burn rate (r) value of the propellants, and (ii) in-. hibitors, which decrease the burn rate value of the propellants. The effective cata-.
Synthesis and Characterization of New Energetic Nitroformate Salts. New energetic nitroformate salts that contain high-nitrogen cations were synthesized by taking advantage of the relatively high acidity of nitroform. All of the new salts have been characterized by elemental, spectral, and thermal analyses.

TNFA, if it can be synthesizes by this route, would be somewhat analogous to nitroformate salts. There would be two extra electrons resonating amongst the 12 oxygen atoms, which is the same ratio as the nitroformate anion.

Abstract. In composite solid propellants, the fuel and oxidizer are held together by a polymer binder. Among the different types of polymeric binders used in solid propellants, hy.
ZnO Twin-Cones: Synthesis, Photoluminescence, and Catalytic Decomposition of Ammonium Perchlorate Inorganic Chemistry. Sun, Qiu, Li and Li Abstract: ZnO twin-cones, a new member to the ZnO family, were prepared directly by a solvothermal method using a mixed solution of zinc nitrate and ethanol.
Abstract. The nitro group in aliphatic and aromatic nitro compounds, which also contain reducible substituents such as alkenes, nitriles, carboxylic acids, phenols, halogens, esters, etc., is selectively and rapidly reduced at room temperature to the corresponding amine in good yield by employing hydrazinium monoformate in the presence of magnesium powder.
The enthalpies of dissolution of nitroform and its ammonium, hydrazinium, guanidinium, and potassium salts in water were measured. The enthalpy of combustion of hydrazinium salt of nitroform was determined by a combustion calorimetry, and its standard enthalpy of formation was calculated.
Two new derivatives of hydrazinium nitroformate (HNF) viz., mono methyl hydrazinium nitroformate (MMHNF) and dimethyl hydrazinium nitroformate (DMHNF) have been synthesized and characterized by elemental, spectral and thermal analysis. The nitration of isopropanol using fuming nitric acid and sulphuric acid yielded nitroform which on neutralization with equivalent quantities of hydrazine.
Technical Approach. Many programs and patents have explored the feasibility of replacing AP with non-halogenated oxidizers, including hydrazinium nitroformate (HNF), ammonium nitrate (AN), ammonium dinitramide (ADN), and hydroxyl ammonium nitrate (HAN).Each of these compounds present significant problems in performance, sensitivity, toxicity, or stability.
