“…The general description of the equilibrium ebulliometer and the disposal of the different elements in the installation can therefore be consulted in previous papers. 4,[10][11][12] It was also necessary to prepare J-type thermocouples with a soldered nut. The nut was threaded onto a bolt which had a hole in its center that perforated entirely, and was welded to the ebulliometer.…”

A new dynamic still for the determination of vapor−liquid equilibrium (VLE) data has been constructed in stainless steel. Both the liquid and vapor phases are recirculated. The operating procedure is based on the Cottrell pump principle. The liquid mixture is placed in an inverted double-walled vessel and heated. The equipment performance has been verified by measurements on mixtures that have been previously studied by various authors. VLE data have been determined for the ethyl acetate + methanol binary system at (0.1, 0.5, and 0.7) MPa. The experimental data have been tested with the point-to-point test of Van Ness, employing the program of Fredenslund, and are shown to be consistent.

“…The equation of Yen and Woods was used for the calculations of liquid molar volumes. The critical properties were taken from literature, and the constants of the Antoine equation for the calculation of the vapor pressures of pure components were employed as in previous works. − , In Table are presented the calculated activity coefficients. All binary mixtures show positive deviations from Raoult’s law.…”

Experimental Determination of Vapor–Liquid Equilibria. Binary Systems of Methyl Acetate, Ethyl Acetate, and Propyl Acetate with 1-Propanol at 0.6 MPa

et al. 2013

Data from isobaric vapor–liquid equilibrium (VLE) for the binary systems methyl acetate, ethyl acetate, and n-propyl acetate with 1-propanol have been determined at 0.6 MPa employing a metal ebulliometer with recirculation of both phases. The thermodynamic consistency of experimental data has been verified with the Van Ness point-to-point test, using the routine in Fortran proposed by Fredenslund et al. The azeotropic point was observed for the binary systems ethyl acetate/1-propanol and propyl acetate/1-propanol. The activity coefficients of the liquid phase were calculated by considering the nonideality of the vapor phase. The binary systems studied show positive deviation from ideal behavior. Predictions obtained from the group contribution models ASOG and different versions of UNIFAC were verified by comparing the values provided by the models with experimental data of VLE.

“…To our knowledge, no previous studies have systematically considered the VLE of all the different isomers of a single linear ester with a common second component. Extensive studies have been done into the phase behavior and mixing properties of binary mixtures of linear esters with various primary and secondary alcohols − as well as with normal alkanes. − These studies have adopted a systematic approach in assessing the effect of varying the alkanolic length of the ester while keeping the acidic chain length constant (or vice versa) on the phase behavior of these esters with a common second component. The choice of an n -alkane as the second component allowed these authors to attribute differences in the observed phase behavior to the dilution or concentration of polar effects due to the presence of the nonpolar alkane.…”

Vapor–Liquid Equilibria Measurements for the Five Linear C₆ Esters with n-Octane

2016

View full text Add to dashboard Cite

Vapor–liquid equilibrium (VLE) data were measured for the five binary systems comprising each of the unbranched constitutional isomers of a C6 ester with n-octane at 60.0 kPa. All five systems exhibited strong positive deviations from ideality and minimum boiling azeotropes due to the fundamental differences in the intermolecular forces of each component in the pair, as well as the closeness of the pure component boiling points at the system pressure. Thermodynamic consistency of all data was shown using the Wisniak L/W and McDermott–Ellis consistency tests, and the data were correlated and predicted with the NRTL and UNIFAC activity coefficient models, respectively. The data illustrated the role of the location of the polar ester functional group on the phase behavior of respective ester structural isomers with a common second component.
