ESDU 81042 gives vapour pressure data for 29 compounds not covered by ESDU 81025. These include chloro, bromo and fluoro as well as nitro, hydroxy and aromatic derivatives. The vapour pressures have been critically evaluated and fitted by a Wagner equation. The coefficients of the equation for each compound are given together with tables of the vapour pressures at 5 K intervals. The values of critical pressure and temperature are given. Where the compound may decompose these are estimated.
