Correlation and Extrapolation in Chemical Engineering of Vapour Pressure Data Using Thermal Data

Vapour pressures are among the most often measured physico-chemical properties. The measurements are most frequent and accurate in the pressure range 10–100 kPa. The determination of vapour pressures in the region below 1 kPa, on the other hand, are difficult, time-consuming and relatively inaccurate. Extrapolation based on vapour pressures measured in a limited range near the boiling point is usually unreliable.
