ESDU 77019:1980

(Scanned original: to be superseded.)

ESDU 77019 gives vapour pressure data for 48 compounds, in the form of tables of temperature at selected vapour pressures and tables of vapour pressure at 5 K intervals for pressures from 0.00001 atmospheres to the critical point. 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 for each compound are given together with values of critical temperature, critical pressure and acentric factor.
