“…Table 4 summarizes details of the selected data sets for the density of toluene from the literature. Although many measurements of the density of toluene were carried out in the past, only the ten data sets of Akhundov and Abdullaev [22], Avelino et al [23], Zéberg-Mikkelsen et al [24], Moravkova et al [25], Watson et al [26], Segovia et al [27], Valencia et al [28], Rowane et al [29], Tay and Trusler [30], and Shchamialiou et al [7] extend into the high pressure liquid region above 35 MPa. The data of Rowane et al have Fig.…”

“…Besides these experimental data sets, Muringer et al [40] and Dhakal et al [8] obtained densities from speed of sound measurements by the method of thermodynamic integration in large parts of the liquid region. Shchamialiou et al [7] applied a method of thermodynamic integration, which can be viewed as inverse to our method, to derive speeds of sound, isobaric and isochoric heat capacities and further properties from experimental density data. [19] are depicted in Figs.…”

“…During the course of this work, three further experimental data sets for the speed of sound and derived properties of liquid toluene were published. Shchamialiou et al [7] measured the speed of sound between 298.15 K and 433.15 K with pressures up to 100 MPa and a relative uncertainty of 0.05 %. In the work of Dhakal et al [8], two data sets are reported.…”

The method of thermodynamic integration is applied to calculate accurate data for the density and isobaric and isochoric heat capacity of toluene and n-butane from speed of sound data sets measured previously in our laboratory. Values for the density and isobaric heat capacity on the initial isobar for the integration are derived from very accurate density and speed of sound data sets using well-known thermodynamic relations. The relative expanded uncertainties (at the 0.95 confidence level) in the derived values for the density and isobaric and isochoric heat capacities are estimated to be 0.011 %, 0.3 %, and 0.4 % for toluene and 0.02 %, 0.5 %, and 0.7 % for n-butane, respectively. Comparisons with experimental data, values of other authors derived by the thermodynamic integration, and equations of state show that our values for both fluids are more accurate than most data available in the literature. Moreover, the domain of the thermodynamic integration for toluene extends down to 240 K and covers lower temperatures than recently considered by other authors. The derived values for the isobaric heat capacity of n-butane fill a gap as this property has hitherto only been measured at ambient pressure. Because of their low uncertainty, the values of the derived properties reported in this work in combination with recent data of other authors are useful for developing new and improved equations of state for both fluids.

Thermodynamic Properties of Liquid Toluene from Speed-of-Sound Measurements at Temperatures from 283.15 K to 473.15 K and at Pressures up to 390 MPa

We report the speeds of sound in liquid toluene (methylbenzene) measured using double-path pulseecho apparatus independently at The University of Western Australia (UWA) and Imperial College London (ICL). The UWA data were measured at temperatures between (306 and 423) K and at pressures up to 65 MPa with standard uncertainties of between (0.02 and 0.04) %. At ICL, measurements were made at temperatures between (283.15 and 473.15) K and at pressures up to 390 MPa with standard uncertainty of 0.06 %. By means of thermodynamic integration, the measured sound-speed data were combined with initial density and isobaric heat capacity values obtained from extrapolated experimental data to derive a comprehensive set of thermodynamic properties of liquid toluene over the full measurement range. Extensive uncertainty analysis was performed by studying the response of derived properties to constant and dynamic perturbations of the sound-speed surface, as well as the initial density and heat capacity values. The relative expanded uncertainties at 95 % confidence of derived density, isobaric heat capacity, isobaric expansivity, isochoric heat capacity, isothermal compressibility, isentropic compressibility, thermal pressure coefficient and internal pressure were estimated to be (0.2, 2.2, 1.0, 2.6, 0.6, 0.2, 1.0 and 2.7) %, respectively. Due to their low uncertainty, these data and derived properties should be well-suited for developing a new and improved fundamental Helmholtz equation of state for toluene.
