EXCESS MOLAR VOLUMES AND VISCOSITIES OF 10 BINARY AND 4 TERNARY LIQUID-MIXTURES

Densities and viscosities of ten binary and four ternary mixtures containing bromoform, bromobenzene, chlorobenzene, toluene, 1,3,5-trimethylbenzene and dimethylformamide at 30, 35 and 40-degrees-C have been measured. Excess molar volumes, apparent values of excess molar viscosities and excess molar Gibbs energy of activation of flow have been calculated for both the binary and ternary mixtures. The results of ternary excess molar volumes have been analysed by using the theoretical models suggested in the literature. The calculated excess quantities have been discussed in terms of the nature of binary and ternary interactions.
