ESDU 80029 gives vapour pressure data for 51 compounds. These include 18 alkanoic acids, 9 alkenoic acids, 6 alkanedioic and alkenedioic acids, 4 hydroxy, alkoxy and oxo carboxylic acids, 4 halogenated acids and 10 anhydrides, including 3 halogenated. 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 temperature and pressure are given. Where the compound may decompose these are estimated.
