ABSTRACT

Excess molar volumes VE, excess molar enthalpies HE, speeds of sound , u and vapour-liquid equilibrium data of 1,3-dioxolane (i) + aniline or N-methyl aniline or o-toluidine (j) binary mixtures have been measured as a function of composition at 308.15K. Speeds of sound and vapour-liquid equilibrium data of (i+j) binary mixtures have been utilized to determine isentropic compressibilities changes of mixing, esE and excess Gibb's free energy GE. The observed data have been analyzed in term of Graph theory which involves the topology of the mixture constituents. It has been observed VE, HE,esE and GE values predicted by Graph theory compare well with their corresponding experimental values.
