| Popis: | International audience; New isothermal vapor-liquid equilibrium (VLE) data for the carbon dioxide + 1,4dioxane system are reported at four temperatures (323.15, 333.15, 343.15, and 353.15) K and pressures up to 122.7 bar. The critical curve was also measured up to 158.8 bar and 420.15 K. Phase behavior measurements were performed in a high-pressure windowed cell with variable volume, using a static-analytical method with phases sampling by rapid online sample injectors (ROLSI) coupled to a gas chromatograph (GC) for analysis. The experimental results of this study are compared with the scarce available literature data. The new and all available literature data for the carbon dioxide + 1,4-dioxane binary system are modelled with the cubic Soave-Redlich-Kwong (SRK) and Peng-Robinson (PR) equations of state (EoS) with classical van der Waals mixing rules (two-parameter conventional mixing rules, 2PCMR). The modelling showed that SRK and PR models can accurately predict the phase behavior of the system studied. |
