The vapor pressure measurements were performed using the static method over the temperature range from 238-308 K. Liquid heat capacities were measured by Tian-Calvet calorimetry in the temperature interval from 258-355 K and were extended by controlled extrapolation by differential scanning calorimetry toward the normal boiling point temperatures. The phase behavior was investigated by DSC from 183 K. The thermodynamic properties in the ideal-gas state were calculated by combining statistical thermodynamics and density functional theory calculations. Scaling factors were evaluated based on measured Raman and IR spectra. Calculated ideal-gas heat capacities and experimental data on vapor pressures, condensed phase heat capacities, and vaporization enthalpies were treated simultaneously to obtain a consistent thermodynamic description.
