VAPOUR PRESSURES OF PURE SUBSTANCES UP TO THEIR CRITICAL POINTS. I: C1 to C8 ALKANES.

ESDU 72028 gives vapor pressure data for 40 compounds, in the form of tables and curves. These include 8 straight and 32 branched chain alkanes. The vapor 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. Tables of temperature for selected values of vapor pressure and tables of vapor pressure at 5 K intervals of temperature are given for pressures from 0. 001 atmospheres to the critical point.
