ESDU 98014 presents vapour pressure data for 31 halogenated benzenes obtained by a critical evaluation of experimental results in the literature. The limited data available were extrapolated using a correlation developed relating the behaviour of the coefficients of the Wagner equation to the latent heat of vaporisation and the compression factor. The Wagner equation was used over a wide temperature range from the melting point to 0.9 of the critical point (or higher when appropriate) and the coefficients are given for each compound. Two tables of vapour pressure calculated using the equation are given: one in SI units at 5 K intervals and one in bars at 5 degree C intervals. A table also gives saturation temperatures at various specified pressures and indicates the possible uncertainty in the calculated values. Values of acentric factor, normal melting and boiling points, and the slope of the saturation temperature versus vapour pressure curve at the normal boiling point are also given together with a list of the sources of data for each compound. Density data for the compounds are given in ESDU 98015 and the choice of critical point values gave the best correlations for both properties.
