    Abstract:

    Henry's law constants and infinite dilution activity coefficients of propane, propene, butane, 2-methylpropane, 1-Butene, 2-methylpropene, trans-2-Butene, cis-2-Butene, 1,3-butadiene, dimethylether, chloroethane, 1,1-difluoroethane, and hexane in tetrahydropyran in the temperature range of (250 to 330) K were measured by a gas stripping method, and partial molar excess enthalpies and entropies were evaluated from the activity coefficients. A rigorous formula for evaluating the Henry's law constants from the gas stripping measurements was used for these highly volatile mixtures. The estimated uncertainties are about 2 % for the Henry's law constants and 3 % for the infinite dilution activity coefficients. The Henry's law constants followed the order of the increasing Henry's law constant with decreases in the normal boiling point temperature of the solutes except for polar solutes. The partial molar excess entropies and enthalpies of the solutes at infinite dilution in tetrahydropyran are smaller than thos...

    Journal of Chemical & Engineering Data, 2004
    Co-Authors: Yoshimori Miyano
    Abstract:

    The Henry's constants and the infinite dilution activity coefficients of propane, propene, butane, isobutane, 1-Butene, isoButene, trans-2-Butene, and 1,3-butadiene in 2-propanol in the temperature range 250 K to 330 K are measured by a gas stripping method. The rigorous formula for evaluating the Henry's constants from the gas stripping measurements is used for these highly volatile mixtures. The accuracy of the measurements is about 2% for Henry's constants and 3% for the estimated infinite dilution activity coefficients. In the evaluations for the infinite dilution activity coefficients, the nonideality of the solute is not negligible, especially at higher temperatures, and the activity coefficients include the estimation uncertainty of about 1%.

    Abstract:

    Abstract The Henry’s constants and the infinite dilution activity coefficients of propane, propene, butane, isobutane, 1-Butene, isoButene, trans-2-Butene and 1,3-butadiene in 1-propanol at T=(260 to 340) K are measured by a gas stripping method. The rigorous formula for evaluating the Henry’s constants from the gas stripping measurements is used for these highly volatile mixtures. The accuracy of the measurements is about 2% for Henry’s constants and 3% for the estimated infinite dilution activity coefficients. In the evaluations for the infinite dilution activity coefficients, the nonideality of solute is not negligible especially at higher temperatures and the estimated uncertainty in the infinite dilution activity coefficients include 1% for nonideality.

  • henry s constants of butane isobutane 1 Butene and isoButene in methanol at 255 320 k

    Abstract:

    Abstract The Henry’s constants and the infinite dilution activity coefficients of butane, isobutane, 1-Butene and isoButene in methanol at 255–320 K are measured by a gas stripping method. The rigorous formula for evaluating the Henry’s constants from the gas stripping measurements is proposed for these highly volatile mixtures. By using this formula, a volume effect of vapor phase and the effect of nonideality of fluids are discussed. In the evaluations for activity coefficients the nonideality of solute was not negligible especially at higher temperatures. The values of Henry’s constants of butane are much different from those of isobutane, while the activity coefficients are not so different to each other. The activity coefficients of butane are about 2.5% greater than those of isobutane, and those of 1-Butene are about 4% greater than those of isoButene.
