Reference Correlation of the Viscosity of Ethylbenzene from the Triple Point to 673 K and up to 110 MPa

A new correlation for the viscosity of ethylbenzene is presented. The correlation is based upon a body of experimental data that has been critically assessed for internal consistency and for agreement with theory . It is applicable in the temperature range from the triple point to 673 K at pressures up to 11 0 MPa . The overall uncertainty of the proposed correlation, estimated as the combined expanded uncertainty with a coverage factor of 2, varies from 1 % for the viscosity at atmospheric pressure to 5% for the highest temperatures and pressures of interest. Tables of the viscosity, generated by the relevant equations, at selected temperatures and pressures , and along the saturation line, are provided. Comparison of viscosity of xylene isomers indicated that at very high temperatures the viscosity correlation of para - xylene has higher uncertainty than previously postulated. Thus, in this work w e also provide a revised viscosity correlation for p -xylene
