ABSTRACT

With densities and ultrasonic speeds, interactions of aniline with ethylene glycol, diethylene glycol and triethylene glycol are measured at T = (293.15-308.15) K. From the densities, the (apparent molar and partial molar) volumes, and are computed. The apparent specific volume and partial specific volume are also evaluated from density data. The (apparent molar and partial molar) isentropic compressions, , and , have been evaluated from measured ultrasonic speeds. The transfer properties such as (partial molar isentropic compression and partial molar volumes) of transfer ( cents , and cents ) are also determined utilizing density and ultrasonic speed data. The pair and the triplet interaction coefficients are computed from (partial molar isentropic compression and partial molar volumes) of transfer. The partial molar expansibility ( . ) and second order derivative ( / ) are also calculated. The parameters hence obtained are conferred in terms of solute-solute or solute-solvent interactions succeeding in present ternary system.
