A fourth parameter to be used in conjunction with Pitzer's acentric factor is proposed to correlate the thermophysical properties of anormal fluids. It is based on the saturated liquid density at a reduced temperature of 0.7. A correlation for saturated liquid densities of anormal fluids is presented to cover a reduced temperature range from 0.42 to 1.0. For four hundred and fifty‐six data points, covering twenty‐one compounds, calculated average and average absolute deviation in predicted saturated liquid densities are −0.05 and 1.11%, respectively.
