ABSTRACT

This paper reports experimental activity coefficients at infinite dilution for 16 solutes (benzene, toluene, ethanol, esters, ketones, and ethers) at different temperatures (308 e T/K e 343) measured with the help of a dilutor technique (inert gas stripping). The activity coefficients obtained are in good agreement with data derived from LLE data. Furthermore, the partial molar excess enthalpies derived from these data are in agreement with the values derived from enthalpy of mixing data.
