Speed of sound, molar volume, and molar isobaric heat capacity for binary liquid mixtures: analysis in terms of van der Waals's one-fluid theory

The speed of sound and excess molar isobaric heat capacity at 298.15 K, and the excess molar volume at 303.15 K are reported for ( n-dodecane + n-hexane). The results, in combination with the excess molar volume at 298.15 K published previously, are used to obtain the interaction parameters a 12 and...

Description
Summary:The speed of sound and excess molar isobaric heat capacity at 298.15 K, and the excess molar volume at 303.15 K are reported for ( n-dodecane + n-hexane). The results, in combination with the excess molar volume at 298.15 K published previously, are used to obtain the interaction parameters a 12 and b 12 for the mixture treated as a pure fluid obeying a generalized van der Waals's equation of state. Similar analyses, using results from our previous investigations, are presented for (di- n-propylether + n-heptane) and (benzene + cyclohexane).
