Isothermal vapor-liquid equilibrium data for the binaries propane-2-propanol and propylene-2-propanol

Vapor−Liquid Equilibrium Data for Propylene + Ethanol, Propylene + MEK, and Propylene + MTBE

“…The present work is part of an experimental program undertaken to confirm the applicability of light hydrocarbons as near critical solvents for this separation problem. Zabaloy et al (1992Zabaloy et al ( , 1993a have obtained experimental evidence that confirms the applicability of propane, propylene, and isobutane to the recovery of dehydrated 2-propanol. Additionally, Zabaloy et al (1994) have shown that propane and isobutane are suitable solvents to recover and dehydrate ethanol and 1-propanol, respectively.…”

(Vapour + liquid + liquid) equilibria and excess molar enthalpies of binary and ternary mixtures of isopropanol, water, and propylene

“…In the upper part of figure 3 the calculated (vapour + liquid) phase equilibrium of the binary system (propylene + isopropanol) is shown in comparison with the data from reference [16]. The (vapour + liquid) equilibrium is rather well represented at each of the three temperatures.…”

“…For both the thermodynamic quantities the regression of the former interaction parameters was developed using both the present experimental data and those from the literature [2,3,[16][17][18][19]. The whole data base for the phase equilibrium and the H E used in this case is presented in tables 5 and 6, respectively.…”

Henry's Constants and Infinite Dilution Activity Coefficients of Propane, Propene, Butane, Isobutane, 1-Butene, Isobutene, trans-2-Butene, and 1,3-Butadiene in 2-Propanol at 250−330 K

“…Therefore, it is considered that the accuracies of the obtained infinite dilution activity coefficients in Table 1 may be within 3%. Figure 1 shows the temperature dependencies of the Henry's constants of the eight gases in 2-propanol in the temperature range 250 K to 330 K. The gas solubilities in 2-propanol were measured for propane, butane, and isobutane by Kretschmer and Wiebe 9 and for propene at 200-400 kPa by Goozechak et al 10 The vapor-liquid equilibrium (VLE) data were measured for propane and propene in 2-propanol by Zabaloy et al, 11 for propene + 2-propanol by Horstmann et al, 12 and for isobutane + 2-propanol by Zabaloy et al 13 In general, it is difficult to estimate the Henry's constants from gas solubility data at atmospheric pressure or VLE data. The VLE and gas solubility data are usually measured at an intermediate concentration, and the smoothed data are obtained from the correlation by using an activity coefficient equation.…”
