Notes:
Abstract Heat capacity, Cp, of benzene and hexafluorbenzene was measured in the liquid phase at atmospheric pressure in the temperature range from 280 K to the boiling point. The results are expressed by the following equations: for C6H6, for C6F6, $$\begin{gathered} C_p = 1.5194 - 1.299x10^{ - 3} T + 6.927 \times 10^{ - 6} T^2 \hfill \\ for C_6 F_6 \hfill \\ C_p = 1.1913 - 1.072x10^{ - 3} T + 3.589 \times 10^{ - 6} T^2 \hfill \\ \end{gathered} $$ where C p is in kJ · kg−1 · K−1 and T is in K. The limiting error of heat capacity calculated from these equations is 0.23% for benzene and 0.18% for hexafluorobenzene. From the data, equations for specific volume, thermal expansion coefficient, and the quantity (δT/δp)s were obtained for benzene and hexafluorobenzene.
