Measurements and calculations leading to the determination of thermodynamic properties for the gaseous and condensed phases of p-xylene (Chemical Abstracts registry number (supplied by the authors) [106-42-3]) are reported. All measurement results reported were obtained with a differential-scanning calorimeter (DSC). The critical temperature was measured by DSC. Saturation heat capacities for the liquid phase between 370 K and 550 K, the critical density and the critical pressure were derived with fitting procedures involving the new DSC results and literature vapor pressures and densities. Results were combined with heat capacities reported in the literature obtained with adiabatic calorimetry and the enthalpy of combustion to derive standard molar entropies, enthalpies, and Gibbs free energies of formation at selected temperatures between 250 K and 550 K. The standard state is defined as the ideal gas at the pressure p ) p°) 101.325 kPa. Standard entropies are compared with those calculated statistically on the basis of assigned vibrational spectra. Results are compared with literature values. Literature vapor pressures, enthalpies of vaporization, virial coefficients, densities, and heat capacities for the condensed and gaseous phases are checked for consistency with the values used in this research.

“…Between the temperatures 280 K and 380 K, the densities of m-xylene are well established with numerous reported values within (0.05%, as shown in Figure 7. Values reported for short temperature ranges between 280 K and 330 K by Jain et al (1994), Naorem and Suri (1993), Aralaguppi et al (1992), Ruiz et al (1989), Suri and Ramakrishna (1975), Petro and Smyth (1958), Donaldson and Quayle (1950), and Timmermans and Hennaut-Roland (1930) are within 0.05% of those in Figure 7 but are not shown for clarity.

Measurements leading to the calculation of the ideal-gas thermodynamic properties for m-xylene are reported. Experimental methods included adiabatic heat-capacity calorimetry (5 K to 430 K), vibratingtube densitometry (323 K to 523 K), comparative ebulliometry (309 K to 453 K), and differential-scanning calorimetry (DSC). The critical temperature was measured by DSC. Saturation heat capacities for the liquid phase between 430 K and 550 K and the critical pressure were derived with the vapor-pressure and DSC results. Results were combined with an enthalpy of combustion reported in the literature to derive standard molar entropies, enthalpies, and Gibbs free energies of formation at selected temperatures between 250 K and 550 K. The standard state is defined as the ideal gas at the pressure p ) p°) 101.325 kPa. Standard entropies are compared with those calculated statistically on the basis of assigned vibrational spectra for the vapor phase. All results are compared with literature values. † Contribution No. 361 from the Bartlesville Thermodynamics Group.

Preliminary models for viscosity, thermal conductivity, and surface tension of pure fluid constituents of selected diesel surrogate fuels

We describe preliminary models for the viscosity, thermal conductivity, and surface tension for pure fluids that are constituents of four surrogate fuels for ultralow-sulfur diesel fuels developed under the auspices of the Coordinating Research Council (CRC). These fluids do not presently have published reference fluid quality models in the open literature, so we provide here preliminary models based on available data as an interim measure to allow calculations of these properties for both the pure fluids and the four surrogate mixtures. Comparisons with selected experimental pure-fluid data are given, and text files compatible with the NIST REFPROP computer program are included as supplementary material. We also present tabulations of the viscosity, thermal conductivity, and surface tension along the bubble point for four surrogate fuels.
