ABSTRACT

The differential ebulliometry method was used to measure activity coefficients at infinite dilution for cresols (2-methylphenol or 3-mehtylphenol) with nonane, decane, or undecane a in a range of temperature from (373 to 433) K. Temperature-dependent parameters were determined for the UNIQUAC model. Densities of binary mixtures of systems containing 2-cresol + nonane or decane or undecane and 3-cresol + nonane or undecane or dodecane have been measured at 308.15 K under atmospheric pressure. With these data, excess molar volumes (VE) have been calculated. The excess molar volumes were fitted to the Redlich-Kister polynomial equation.
