Volumes of mixing of ternary alkane mixtures with branched chain components

Abstract

Measurements at 25 °C are reported for the volumes of mixing of binary mixtures of n-dodecane + 2 methyl pentane and of ternary mixtures created by mixing an equimolar mixture of (n-decane + n-tetradecane) with each of the isomers of hexane. The results are compared with the work of Hamam etal. for binary mixtures of n-dodecane with the hexane isomers and shown to be in accord with the principle of congruence within the limits of experimental accuracy of the measurements.
