Abstract

Contradictory literature data on thermal stability, some methods of synthesis, and thermodynamic characteristics of nitryl fluoride have been considered and analyzed. Reliable estimates of reaction enthalpies have been obtained: 2FNO2 = 2FNO + O2, ΔrH°(0) ≥ 173.5, NO2 + 2CoF3(c) = FNO2 + Co2F5(c), ΔrH°(0) = –7.4; 3/2N2O4 + NaF(c) = FNO2 + NO + NaNO3(c), ΔrH°(0) = 11.3 kJ/mol. A new value of the enthalpy of formation of nitryl fluoride ΔfH°(FNO2(g), 0) = –161 ± 15 kJ/mol has been recommended. For the interaction of FNO2 with V2O5(c) as an example, the impossibility of formation of crystalline vanadium pentafluoride has been demonstrated.
