Abstract: The saturated liquid line of the systems nitrogen (N2) + diethyl ether and N2 + 1,1,1,2,2,4,5,5,5-nonafluoro-4-(trifluoromethyl)-3-pentanone (Novec 649) is measured along three isotherms, that is, 390, 420, and 450 K and 360, 390, and 420 K, respectively. The employed gas solubility apparatus, based on the synthetic method, allows to measure points up to the critical region of these mixtures. The experimental data are used to correlate the Peng–Robinson and PC-SAFT equations of state (EOS). For the parametrization of the system, N2 + diethyl ether the Peng–Robinson EOS is combined with the Huron–Vidal mixing rule and the non-random two-liquid (NRTL) excess Gibbs energy model; for the system N2 + Novec 649 the quadratic mixing rule is used.
