Chlorodifluoroamine is an inorganic chemical compound of nitrogen, chlorine, and fluorine with the molecular formula NClF2.[1][2]
Synthesis
Chlorodifluoroamine can be synthesized by the effect of fluorine on sodium azide in the presence of sodium chloride:[3]
- 2 F2 + NaN3 + NaCl → NClF2 + 2 NaF + N2
The effect of fluorine and chlorine on sodium azide also forms the compound:
- 3 F2 + Cl2 + 2 NaN3 → 2 NClF2 + 2 NaF + 2 N2
Also, the reaction of ammonium chloride with fluorine makes it:
- NH4Cl + 3 F2 → NF2Cl + 4 HF
Other methods of synthesis are also known.[4]
Physical properties
The compound forms a colorless air-stable gas[5] that decomposes when heated (sometimes with an explosion).
Chemical properties
The compound decomposes in several ways when heated:
- 2 NClF2 → N2F2 + Cl2
- 6 NClF2 → 4 NF3 + N2 + 3 Cl2
