Bromodifluoromethane or Halon 1201 or FC-22B1 is a gaseous trihalomethane or a hydrobromofluorocarbon.

Synthesis

It can be prepared through the reaction of hydrogen and dibromodifluoromethane at temperature in range 400–600 °C.^[1]

Critical point data: T_c = 138.83 °C (411.98 K); p_c = 5.2 MPa (51.32 bar); V_c = 0.275 dm³·mol⁻¹.

Bromodifluoromethane was used as a refrigerant and in fire extinguishers. It is a class I ozone depleting substance with ozone depletion potential ODP = 0.74. It was banned by Montreal Protocol in 1996.
