Abstract: | Surface tensions, surface tension deviations, densities, and excess molar volumes of binary mixtures of carbon tetrachloride (CCl4) with dimethylsulfoxide (DMSO), diethylsulfoxide (DESO), dipropylsulfoxide (DPSO), and dibutylsulfoxide (DBSO) have been determined over the entire composition range at (298.15 and 313.15) K. The results were fitted by the Redlich–Kister polynomial equation and the corresponding binary coefficients have been derived.The obtained excess quantities show that both charge-transfer complex formation between CCl4 and dialkylsulfoxides (DASO) molecules and on the other hand sulfoxides’ chain length are crucial factors conditioning the excess thermodynamic properties of (CCl4 + DASO) binary mixtures. |
