Volumetric behaviour of ternary organic liquid mixtures containing dimethylsulphoxide, 1,2-dichlorobenzene and 1-alkanols at 303.15Â K

Excess molar volumes V123E of six ternary mixtures were reported at 303.15 K. Dimethylsulphoxide (DMSO) and 1,2-dichlorobenzene (1,2-dcb) served as common components. 1-Alkanols namely 1-propanol, 1-butanol, 1-pentanol, 1-hexanol, 1-heptanol and 1-octanol were chosen as non-common components. The experimental data exhibit an inversion in sign in all the ternary mixtures except in the mixture that contains 1-octanol. The experimental data were compared with empirical relations and these were analysed interms of intermolecular interactions and constituent binaries.
