The bubble point pressures for chlorodifluoromethane (R22) + 1,2-dichloro-1,1,2,2-tetrafluoroethane (R114), bromotrifluoromethane (R13B1) + 1,2-dichloro-1,1,2,2-tetrafluoroethane (R114), and bromotrifluoromethane (R13B1) + chloropentafluoroethane (R115) were measured by a static method. Measurements were made at various compositions at temperatures from 298.15 K to near their critical temperature. The uncertainty of the pressures was estimated to be no greater than [plus minus]0.3%. The bubble point pressures for pure substances were correlated by the Wagner equation, and those for the mixtures were also correlated by the Wagner equation, using a corresponding states principle.
