Abstract

An apparatus for the determination of vapour‐liquid equilibria at constant pressures within the range of 760 to 10 mm Hg is described.

The apparatus can produce eight pairs of samples of coexisting vapour and liquid, evenly distributed over the concentration range in one run within two hours.

As a proof of its operation the results obtained with six binary systems are recorded. The systems investigated are:

Carbon tetrachloride‐benzene.

Carbon tetrachloride‐toluene.

Benzene‐dichloroethane.

n‐heptane‐methylcyclohexane.

methylcyclohexane‐toluene.

n‐decane‐trans‐decahydronapththalene.

The results obtained agree with a thermodynamic criterion which is discussed separately.

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
