Abstract :

The dynamic shear viscosity of a binary liquid mixture phenol â?? water has been measured at different temperatures and concentrations. The critical temperature Tc and critical concentration are found to be 67.0?ºC and 33.90% by weight of phenol respectively, the critical density ρc is measured to be 0.8952 gm/cm3.The critical and background amplitudes of specific heat at constant pressure are calculated to be 78.117 J/kg.K and 85.292 J/kg.K respectively. The pressure derivative of the critical temperature along the critical line Tc is calculated to be 9.722 ??10-6 K/Pa. The dynamic shear viscosity of binary liquid mixture phenol â?? cyclohexane has been measured at different temperatures and concentrations. The critical temperature Tc and critical concentration are found to be 17.0 ?ºC and 2.70% by weight of phenol respectively. The critical density ρc is measured to be 0.7627 gm/cm3.The critical and background amplitudes of isobaric thermal expansion coefficient ?±pc and ?±pb are calculated to be 4??10-6 K-1, 6??10-4 K-1 respectively. The pressure derivative of the critical temperature xc for the binary is calculated to be 1.083 ??10-8 K/Pa. The universal quantityR+?¾ of both binary liquid critical mixtures phenol â?? water and phenol â?? cyclohexane are calculated to be 0.2716and 0.2699 respectively. The values are in a good agreement with the theoretical value of R+?¶. The two binary liquid critical mixtures belong to the class of universality "Two â?? Scale â?? Factor Universality".
