✦ Synopsis

The application of rigorous thermodynamic methods allows the calculation of vapourliquid equilibrium data for binary systems from measurements of the total vapour pressures exerted by the liquid phase. Of the methods known, integration of the coexistence equation is considered most convenient. Exact forms of this equation are derived for both the constant-temperature and constant-pressure cases of binary equilibria. Applications are made to the ethanol-toluene system.
