Abstract

We present a new wide-ranging correlation for the viscosity of propane-1,2-diol (propylene glycol) based on critically evaluated experimental data. The correlation is designed to be used with an existing equation of state, and it is valid from the triple point to 452 K, at pressures up to 245 MPa. The estimated uncertainty is 4.5 % (at the 95 % confidence level), except in the dilute-gas region which is estimated to be 15 %, as there are no measurements in this region for comparison. The correlation behaves in a physically reasonable manner when extrapolated to 680 K and 350 MPa, however care should be taken when using the correlations outside of the validated range.
