Molecular interaction studies in the ternary mixture of cyclohexane plus toluene+2-propanol

Ultrasonic velocities. densities and viscosities have been measured for the ternary system of cyclohexane + toluene + 2-propanol at 303, 308 and 313 K . From these data, acoustical parameters such as adiabatic compressibility, free length, free volume and internal pressure have been estimated using t he standard relations. The results have been analysed on the basis of varia tions in ultrasonic velocities and free lengths. Cyclohexane-toluene comple xes are observed to be broken by 2-propanol. The presence of weak interacti ons are noticed in the ternary system.
