Tracer Diffusion and Shear Viscosity for the System Isobutyric Acid–Water near the Critical Mixing Point

Tracer diffusion coefficients of 14C isobutyric acid in mixtures of isobutyric acid–water have been measured over the entire concentration range at ε = 3.9 × 10−4 above the critical point using the diaphragm cell technique. No anomaly was detected. The temperature dependence of the shear viscosity c... View More
