ESDU 78011:1981

(Scanned original: to be superseded.)

ESDU 78011 gives vapour pressure data for 72 compounds, in the form of tables. The vapour pressures have been critically evaluated and their temperature variation fitted by an equation in the form of a series of Chebyshev polynomials. The constants of the Chebyshev equation are given, together with the constants of the approximately equivalent Wagner equation. Also tabulated are values of critical temperature, critical pressure and acentric factor. Tables of temperature at selected vapour pressures and tables of vapour pressures at 5 K intervals are given for pressures from 0.00001 atmospheres to the critical point.
