ESDU 81003 gives vapour pressure data for 53 compounds. These include 6 isovalerates, 12 esters of higher alkanoic acids (hexanoates etc), 10 acrylates and methacrylates, 5 oxalates and 10 other esters of dicarboxylic acids, and esters of hydroxy carboxylic acids, oxo carboxylic acids and halogenated carboxylic acids. 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.
