| Abstract: | 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 hydrate yielded HNF, whereas neutralization with methyl
hydrazine and dimethyl hydrazine solution in xylene solvent gave title
compounds MMHNF and DMHNF respectively. MMHNF and DMHNF were thermally stable
up to 128-137°C whereas the decomposition of HNF
commenced at 120°C. The impact sensitivity data
established relatively less susceptibility of MMHNF and DMHNF than that of the
HNF. Performance of MMHNF and DMHNF was also predicted theoretically by
applying Linear Output Thermodynamic User friendly Software for Energetic
Systems (LOTUSES) code. Out of the three compounds synthesized, HNF finds
potential application as a eco-friendly oxidizer and MMHNF may find application
as a potential high performance energetic material and DMHNF appears to be
potential ingredient for melt castable high explosive formulations. |
