Thermodynamic properties of mixtures

New measurements have been made for the viscosity of toluene between 255 K and 323 K at pressures up to approximately 400 MPa with a falling-body viscometer. These extend earlier high-pressure measurements below 298 K. The measurements form part of an intercomparison of high-pressure viscometers by the IUPAC Physical Chemistry Division, Commision 1.2, Subcommittee on Transport Properties. A revised correlation function is used to represent the results with a repeatability of ±0.5%. The uncertainty is estimated at ±1%.
