Isobaric Vapor−Liquid Equilibria for Binary and Ternary Mixtures of Dipropyl Ether, 1-Propyl Alcohol, and Butyl Propionate
2006
Consistent vapor−liquid equilibrium (VLE) data at 101.3 kPa have been determined for the ternary system dipropyl ether + 1-propyl alcohol + butyl propionate and two constituent binary systems: dipropyl ether + butyl propionate and 1-propyl alcohol + butyl propionate. The dipropyl ether + butyl propionate system exhibits ideal behavior, and the 1-propyl alcohol + butyl propionate system shows positive deviations from Raoult's law. No additional azeotropes are present. The activity coefficients of the solutions were correlated with its composition by the Wilson, NRTL, and UNIQUAC models. The ternary system is well-predicted from binary interaction parameters. Butyl propionate breaks the dipr…

Evaluation of Diethyl Carbonate and Methyl Isobutyl Ketone as Entrainers for the Separation of 1-Hexene and n-Hexane
2017
Diethyl carbonate and methyl isobutyl ketone are tested as possible entrainers for separating 1-hexene and n-hexane by extractive distillation. For this purpose, isobaric vapor–liquid equilibrium (VLE) data at 100 kPa have been obtained for the two ternary systems formed by the two hydrocarbons and one of the selected solvents: 1-hexene + n-hexane + diethyl carbonate and 1-hexene + n-hexane + methyl isobutyl ketone. VLE data for the following constituent binary systems have also been determined: 1-hexene + diethyl carbonate, n-hexane + diethyl carbonate, 1-hexene + methyl isobutyl ketone, and finally n-hexane + methyl isobutyl ketone. All binary systems present moderate positive deviations …
Isobaric Vapor−Liquid Equilibria for Binary and Ternary Mixtures of Diisopropyl Ether, 2-Propyl Alcohol, and n-Butyl Propionate at 101.3 kPa
2009
Consistent vapor−liquid equilibrium data at 101.3 kPa have been determined for the ternary system diisopropyl ether (1) + 2-propyl alcohol (2) + n-butyl propionate (3) and two constituent binary systems: diisopropyl ether (1) + n-butyl propionate (3) and 2-propyl alcohol (2) + n-butyl propionate (3). The diisopropyl ether (1) + n-butyl propionate (3) system does not present deviation from ideal behavior, and the 2-propyl alcohol (2) + n-butyl propionate (3) system shows light positive deviation from Raoult’s law. The activity coefficients of the solutions were correlated with their compositions by the Wilson, NRTL, and UNIQUAC models. Wisniak−Tamir equations were used to correlate the boili…
