    Heats of solution of gaseous hydrocarbons in water at 15, 25, and 35°C (1985)

    Notizen: Abstract Calorimetrically measured heats of solution of eleven hydrocarbon gases into water are reported at 15 and 25°C. Gases studied are methane, ethane, propane, n-butane, 2-methylpropane, 2,2-dimethylpropane, cyclopropane, ethene, propene, 1-butene, and ethyne. These values in combination with previous results are used to derive heat capacity changes at 25°C. Comparison of enthalpy and heat capacity values with those from other studies shows satisfactory agreement. Correlation of the heat capacity change with the number of water molecules in the first solvation shell of the solute suggests that the observed heat capacity changes are primarily due to changes in the water molecules in this solvent shell.

    Heats of solution of several freons in water from 5 to 45°C (1987)

    Notizen: Abstract An extensive set of measurements of the heats of solution of a number of fluorine-containing gases (CCl2F2, CClF3, CBrF3, CF4) have been performed from 5 to 45°C. The temperature dependence allows accurate determination of the heat capacity change in the solution process as a function of temperature. To a first approximation these heat capacity results agree with the predictions of the simple two energy state model for water molecules in the first solvation shell. The further extension of the general applicability of this model, originally developed to account for the thermodynamic properties of solvation of hydrocarbon and other small apolar gases in water, suggests that the unique thermodynamic properties of hydrophobic solvation are largely determined by the water molecules in the first solvation shell.

    Heats of solution of gaseous hydrocarbons in water at 25°C (1984)
    Springer

    Notizen: Abstract The heats of solution at 25°C for a number of hydrocarbon gases are reported as measured by a calorimetric method. There is excellent agreement between the standard enthalpy changes of solution measured calorimetrically and those derived from high precision temperature dependent solubility measurements. However the calorimetrically determined standard enthalpies of solution of a number of gases are greatly improved over values obtained from low precision temperature dependent solubility measurements. A method is presented to readily estimate the standard errors in the standard enthalpy change for any process derived from the temperature dependence of the equilibrium constant for the process. Comparison of the standard enthalpies and entropies of solution of hydrocarbon gases in water shows that the standard free energies of solution for all hydrocarbon gases investigated are dominated by unfavorable entropy contributions. A strong linear correlation between the standard entropy of solution and the number of hydrogens in the hydrocarbon molecule is found. This correlation suggests that the hydrocarbon hydrophobic effect is regulated by the number of allowable configurations of a water molecule in contact with each C−H group.
