Isobaric Vapor-Liquid Equilibrium Data for Six Binary Systems: Prop-2-en-1-ol (1)-Hexan-2-ol (2), Prop-2-en-1-ol (1)-Hexan-2-one (2), Hexan-2-one (1)-Hexan-2-ol (2), Prop-2-en-1-ol (1)-4-Methyl-pentan-2-ol (2), Prop-2-en-1-ol (1)-4-Methyl-pentan-2-one (2), and 4-Methyl-pentan-2-one (1)-4-Methyl-pentan-2-ol (2) at 101.32 kPa

In this work, isobaric vapor-liquid equilibrium (VLE) measurements were conducted for the binary systems of prop-2-en-1-ol (1)-hexan-2-ol (2), prop-2-en-1-ol (1)-hexan-2-one (2), hexan-2-one (1)-hexan-2-ol (2), prop-2-en- 1-ol (1)-4-methyl-pentan-2-ol (2), prop-2-en-1-01 (1)-4-methyl-pentan-2one (2), and 4-methyl-pentan-2-one (1)-4-methyl-pentan-2-ol (2) to assist with the design of the separation process by distillation. Measurements were determined using Fischer VLE 602 equipment at 101.32 kPa. The thermodynamic consistency of the measured VLE data was validated by modified Herington, Van Ness, pure component consistency, and Redlich-Kister total area tests. Moreover, data sets were correlated using the nonrandom two-liquid (NRTL), universal quasichemical (UNIQUAC), and Wilson thermodynamic models to obtain the binary interaction parameters using the Aspen Plus V11 commercial software. The root-mean-square deviations (RMSDs) of the equilibrium temperature (T) and the vapor mole fraction (y,) were less than 0.24 and 0.0089, respectively, which indicate that these three thermodynamic models can be used to correlate the six binary systems and therefore they can be employed for the development and optimization of the separation process.

Automated summary

In this study, isobaric vapor-liquid equilibrium measurements were carried out for six binary systems to aid in distillation process design. The data obtained was validated for thermodynamic consistency and correlated using different models to determine binary interaction parameters. The results showed that the models used were effective in correlating the six binary systems, making them suitable for separation process development and optimization.
