Abstract : This critical review is a study of the vapor pressure-boiling point data from the triple point to the critical point for CH4-aXs (X=Br,I) and CH4-(a+b+c+d) FaClbBrcId halomethanes. The available data are carefully analyzed and the 'best' data selected. The selection procedure is discussed. Uncertainties in the selected temperatures and pressures are reported. The selected data were fitted to the Antoine equation for data up to 1500 mm Hg pressure and the Wagner equation for data up to the critical point. Antoine constants for nineteen compounds and the Wagner constants for five compounds are reported. The enthalpy of vaporization at 298.15 K and at the normal boiling point have been computed.
