ABSTRACT

In this work, the isobaric vapor liquid equilibrium (VLE) for the ethanol (1) + 3-methyl-1-butanol (2) system at three different pressures is reported. Measurements were done in a dynamic equilibrium cell (Fischer Labodest VLE 602) at 50.66, 101.33 and 151.99 kPa. The experimental data were tested for thermodynamic consistency with total area, point, Van Ness, and Herington tests. Herington test was slightly modified considering the Hm/ GEm relation. Data were correlated using the NRTL and UNIQUAC activity models. NTRL showed the lowest deviation with respect to the experimental data at the three operating pressures. Quality of regressed parameters for this system was tested comparing results with isothermal equilibrium data reported elsewhere.
