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

Abstract

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-ol (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 i ) 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.

Thermodynamic Behavior of the (Methylcyclopentane + Ethyl Acetate) Binary Liquid Mixture: Density at Several Temperatures and Vapor–Liquid Equilibrium at 25, 50, and 101.3 kPa

“…VLE data were measured by using a recirculation ebulliometer (Labodest VLE 602, ILUDEST, Germany). This commercial apparatus is routinely employed to acquire isobaric VLE data under low pressure and is extensively described in our previous works , and in many other studies. ,− Figure depicts the experimental VLE device.…”

Simulation Process for Allyl Alcohol Production via Deoxydehydration of Glycerol

“…Therefore, to improve the reliability of the column distillation unit, binary coefficients based on the UNIQUAC thermodynamic model were employed (Equation ( 2)). The binary coefficients of mixtures such as allyl/2-hexanone, allyl/2-hexanol and 2-hexanone/2-hexanol obtained via data regression of vapour-liquid equilibrium (VLE), were taken from [11]. Allyl alcohol/water, 2-hexanol/water and 2-hexanone/water binary coefficients were obtained from the Aspen Plus database.…”

“…In the first step, the DODH reaction of glycerol to allyl alcohol was performed to obtain the kinetic data required for the design of the conversion operation. Furthermore, in order to improve the reliability of the separation process, accurate binary coefficients of UNIQUAC thermodynamic model were calculated using data regression of vapour-liquid equilibrium (VLE) reported in a previous study [11]. The kinetic data from the DODH reaction and the thermodynamic data from the VLE data regression were used for the simulation process performed using the Aspen Plus software.…”

Density, Excess Molar Volume and Vapor–Liquid Equilibrium Measurements at 101.3 kPa for Binary Mixtures Containing Ethyl Acetate and a Branched Alkane: Experimental Data and Modeling

“…Isobaric vapor-liquid equilibrium measurements for pure components and mixtures were performed using a recirculation ebulliometer (Labodest VLE 602, ILUDEST, Waldbüttelbrunn, Germany) equipped with a Cottrell pump. This type of equipment is routinely employed for low-pressure VLE measurements and extensively described in the literature [32][33][34][35][36].…”
