Thermal decomposition of energetic materials 67. Hydrazinium nitroformate (HNF) rates and pathways under combustionlike conditions
- Univ. of Delaware, Newark, DE (United States). Dept. of Chemistry
Hydrazinium nitroformate (HNF), N{sub 2}H{sub 5}[c(NO{sub 2}){sub 3}], holds promise as a clean-burning,high-energy oxidizer for solid rocket propellants. By using T-jump/FTIR spectroscopy, the thermal decomposition process is outlined in the 130--400 C range, which includes surface melt/foam formation and self-ignition events. Reaction regimes containing evaporation, conversion to NH{sub 4}[C(NO{sub 2}){sub 3}], and progressive decomposition into CO{sub 2}, CO, N{sub 2}O, NO, and H{sub 2}O are observed. Based on the products these reaction regimes become increasingly exothermic at higher temperature. Decomposition induction-time kinetics (E{sub a} = 25 kcal/mol, ln B(s) = 25.3) of the melt/foam layer were determined from time-to-exotherm data and give reasonable agreement with the measured combustion characteristics.
