Reference Correlation of the Viscosity of Toluene from the Triple Point to 675 K and up to 500 MPa

This paper contains new, representative reference equations for the viscosity of toluene. The equations are based in part upon a body of experimental data that have been critically assessed for internal consistency and for agreement with theory whenever possible.

Summary:This paper contains new, representative reference equations for the viscosity of toluene. The equations are based in part upon a body of experimental data that have been critically assessed for internal consistency and for agreement with theory whenever possible. The correlations are valid from the triple point (178.0 K) to 675 K, and at pressures up to 500 MPa. The estimated uncertainty at a 95% confidence level varies depending on the region of temperature and pressure from a low of 0.3% for the low-density gas at temperatures from 305 to 640 K at pressures to 0.3 MPa (essentially the uncertainty of the best experimental data) to 0.7% for the saturated liquid at temperatures from 263 to 373 K, to 5% for the low-temperature liquid from 187 to 210 K at pressures to 15 MPa.
