Critical Behavior of the Ultrasonic Attenuation for the Binary Mixture of Water and Phenol
The dynamic shear viscosity of the binary liquid mixture water – phenol was measured for different temperatures and concentrations using the glass capillary and digital viscometers. Dynamic shear viscosity anomaly was detected near the critical temperature Tc = 67.0 °C and the critical concentration xc = 33.9% by weight of phenol. The specific heat at constant pressure was calculated using the two scale factor universality and found to be 242 J/(kg K). The critical and the background isobaric thermal expansion coefficients were determined and found to be 2.73 · 10–3 °C–1 and 22.6 · 10–3 °C–1 respectively. Ultrasonic attenuation data at 9, 15, 30 and 35 MHz were analyzed using the dynamic scaling theory of Ferrell and Bhattacharjee. The values of αc/f 2 versus f –1.06 yields a straight line as predicted by the theory. The experimental values of α(xc, T)/αc (xc, Tc ) for water – phenol were compared to the scaling function F (ω*) and showed good agreement with the theory.
