The principle of congruence for mixtures of n-alkanes

Abstract

Brønsted and Koefoed's principle of congruence for mixtures of n-alkanes is given a general analytical form. It is shown that the volumes of mixing of n-pentane + n-hexadecane, determined experimentally by Desmyter and van der Waals, may be used in conjunction with the principle of congruence to predict correctly the volumes of mixing of the five other pairs of n-alkanes which have been studied by the same authors.
