New experimental densities and surface tensions for binary mixtures of {heptane + 1-butanol, 1-hexanol, 1-octanol} in a temperature range (288.15, 293.15, 298.15, 303.15, 308.15) K are reported the whole composition range. Densities were measured with an Anton Paar DMA 4500 densimeter. Surface using Lauda TVT2 automated tensiometer, which uses principle pending drop volume. The data pure liquids have been used to calculate excess molar volumes tension deviations as function mole fractions.
A description of the volumetric behaviour segregated hydrofluoroethers has been carried out using PC-SAFT EOS. Characteristic parameters for several molecules were calculated where experimental data available, and accurate results obtained compressed saturated liquid density estimation, as well saturation curves. functional group contribution scheme is proposed also calculation mentioned EOS characteristic parameters, this approach reproduces adequately dependence on molecular structure in...
A new group-contribution method to obtain the PC-SAFT molecular parameters of nonassociated compounds (linear alkanes, branched linear monoethers, and esters) is developed on basis their regular trends against mass. The takes into account proximity effect among all functional groups a molecule in order describe deviations shorter chain from trend observed for larger ones. scheme considers as combination reference functional-group mutual perturbations, which are responsible Both types (the...
A novel refrigerant−absorbent system for absorption refrigeration based on ionic liquids as absorbents and a fluoroalcohol the refrigerant is analyzed. New data of densities at several temperatures in 283.15−333.15 K range pressures up to 40 MPa have been measured. Experimental used study behavior influence temperature, pressure, composition isothermal compressibility isobaric thermal expansion coefficient. In addition, vapor saturated density 2,2,2-trifluoroethanol were determine PC-SAFT...
A new perturbative group-contribution method has been recently developed (J. Vijande, M. Piñeiro, J. L. Legido, D. Bessières, Ind. Eng. Chem. Res. 2010, 49, 9394) that is intended to obtain the PC-SAFT molecular equation of state characteristic parameters nonassociating compounds on a functional group contribution scheme basis. The takes into account proximity effect among groups within molecule in order describe deviations shorter chain molecules' from regular trend observed for longer...
This work aims to experimentally determine the excess molar enthalpies at 298.15 K and atmospheric pressure for ternary mixture {x1 methyl tert-butyl ether (MTBE) + x2 1-pentanol (1 − x1 x2) heptane} corresponding binary system {x x) heptane}, across whole composition range. The enthalpy of is positive throughout Except a region around compositions rich in 1-pentanol, contribution also its representation asymmetric. A systematic review currently accessible literature on mixtures containing...
Densities at high pressures for the binary mixture of methylnonafluorobutyl ether + hexane were measured, as well those corresponding to both pure fluids, in a pressure range from (0.1 25) MPa and temperatures (283.15, 298.15, 313.15) K. A vibrating tube densimeter connected high-pressure measuring cell was used density determination. Experimental data fitted using modified Tait equation. From this set experimental data, excess molar volumes calculated then correlated temperature-...
Experimental high-pressure density data for the binary mixture of methyl nonafluorobutyl ether + hexane were determined. The pressure range considered was 0.1 to 25 MPa, and densities measured along three isotherms, at temperatures (283.15, 298.15, 313.15) K. An Anton Paar DMA 4500 vibrating-tube densimeter, connected a measuring cell, used measurement. fitted using modified Tait equation. Excess molar volumes as well calculated correlated, Redlich−Kister equation, which includes...
