Critical Opalescence

The coexistence curve and critical opalescence of a binary liquid mixture, triethylamine–water, have been reinvestigated. The measurements showed that the coexistence curve appears to follow a cubic relation to within about 0.003° of the critical solution temperature, and in this range, there is no evidence of a flat region. Furthermore, within the range of the values of s/λ(where s = 2 sin (θ/2), λ = wavelength in the medium, and s/λ varied from 1.2 × 10−4 to 7.0 × 10−4 Å−1) and temperatures studied, the light scattering data are in good agreement with the Debye theory (J. Chem. Phys. 31, 680 (1959)). The molecular interaction range of Debye was found to be 5.1 ± 0.3 Å.

We use the model system ethanol–dodecane to demonstrate that giant critical fluctuations induced by easily accessible weak centrifugal fields as low as 2000g can be observed above the miscibility gap even far from the critical point of a binary liquid mixture.
