The liquid molar volumes of CH[sub 2]FCF[sub 3], CH[sub 3]CClF[sub 2], and CH[sub 3]CHF[sub 2] and the binary mixtures of CHClF[sub 2] + CH[sub 3]CClF[sub 2] and CHClF[sub 2] + CH[sub 3]CHF[sub 2] have been measured in the temperature range 260-320 K. Characteristic volumes for CH[sub 2]FCF[sub 3], CH[sub 3]CClF[sub 2], and CH[sub 3]CHF[sub 2] required for the Thomson-Brobst-Hankinson correlation have been determined. Interaction parameters for the equations of state have been determined from experimental data. In a comparative study, the deviation between experimental data and calculated data from three correlation methods is presented. The three methods are the liquid volume correlation according to Thomson-Brobst-Hankinson and the two equations of state according to Carnahan-Starling-de Santis and Lee-Kesler-Ploecker. The Thomson-Brobst-Hankinson correlation gives the least deviation of the three methods studied, for both pure components and mixtures. Of the two equations of state, the Carnahan-Starling-de Santis equation gives the best agreement with experimental data.
