ABSTRACT

The differential ebulliometry method was used to measure activity coefficients at infinite dilution for cyclohexylamine with octane, toluene, ethylbenzene, and aniline in a temperature range from (353 to 403) K. NRTL and UNIQUAC parameters have been determined with these data and with vapor-liquid equilibrium data (VLE) from the literature. In this context P-x-y data were measured for the system cylcohexylamine + toluene at (333.15 and 363.15) K. Excess molar volumes were obtained by density measurements of binary mixtures of cyclohexylamine + heptane, octane, nonane, decane, undecane, aniline, and water at 303.15 K under atmospheric pressure. The excess molar volumes were fitted to the Redlich-Kister polynomial equation.
