Reference Correlations of the Viscosity and Thermal Conductivity of Acetone from the Triple Point to High Temperatures and Pressures

Abstract

This paper presents new wide-ranging correlations for the viscosity and thermal conductivity of acetone (2˗propanone or dimethyl ketone) based on critically evaluated experimental data. Both correlations are designed to be used with a Helmholtz-energy equation of state (EOS) that extends from the triple point to 550 K, at pressures up to 700 MPa. The viscosity correlation is valid from the triple point to 550 K and up to 162 MPa pressure, while the thermal conductivity is valid from the triple point to 550 K and 700 MPa. The estimated uncertainty (at a 95 % confidence level) for the viscosity varies from a low of 2 % for the low-pressure gas (p < 0.5 MPa) to 5.5 % for the liquid phase at pressures up to 162 MPa, and for thermal conductivity varies from a low of 3.5% for the low-pressure gas up to 6.2% for the thermal conductivity at pressures up to 700 MPa.
