Reaction Conditions

Reaction Steps

Into a multineck glass reactor equipped with: magnetic entrainment mechanical stirrer, reflux cooler, thermocouple, inner plunging pipes for introducing the reagents, and maintained at a temperature of -70° C., there were simultaneously fed--after having introduced 75 ml of dichlorodifluoromethane--0.75 l of bis(fluoroxy)difluoromethane at a flowrate of 0.375 l/h diluted with N2 (0.5 l/h) and bromotrifluoroethylene (5.4 g/h) for 2 hours.
