Notes:
Molar volumes were measured and partial molar volumes were calculated in the supercritical region, including the vicinity of the critical locus, lor compositions of 1.8 to 20 mole % n-heptane. Molar volumes can he represented, to a reasonable approximation, by the Flory-OrwollVrij (FOV) reduced equation of state. A better fit of the data is possible if the three exponents in the FOV equation are adjusted The irodified FOV equation or the Redlich-Kwong equation, with parameters idjusted to fit the critical locus, can in general represent the partial molar rolumcs adequately along the critical locus only. The prediction of the imposition-dependence of the partial molar volumes is only qualitatively successful at best.
