Temperature Dependences of Limiting Activity Coefficients, Henry’s Law Constants, and Derivative Infinite Dilution Properties of Lower $(C1–C5)$ 1-Alkanols in Water. Critical Compilation, Correlation, and Recommended Data

A comprehensive review is presented of experimental data on the limiting activity coefficients $γ1∞$⁠, infinite dilution partial molar excess enthalpies $H¯1E,∞$ and heat capacities $C¯p,1E,∞$ of lower 1-alkanols $(C1–C5)$ in water. For each alkanol, the compiled data are critically evaluated and correlated with a suitable model equation providing adequate simultaneous description of the equilibrium measurements and the calorimetric information. As a result, recommended thermodynamically consistent temperature dependences of $γ1∞$⁠, $H¯1E,∞$⁠, and $C¯p,1E,∞$ of superior accuracy are established in the range from the melting point to the normal boiling point of water. In addition, by employing literature data on the respective residual properties of the pure 1-alkanols, analogous recommendations are also derived for the temperature dependences of the Henry’s law constants, hydration enthalpies, and hydration heat capacities. Evolution of the various infinite dilution thermodynamic properties of aqueous 1-alkanols with temperature and homologous series is briefly discussed.
