TL;DR: The application of the distortion-sensitive, derivative-based procedure revealed a limited adequacy of the Vogel-Fulcher-Tammann parametrization and a superiority of the critical-like description tau proportional to (T - T(C) ), phi(') = 9-11.5, on approaching the glass temperature (T(g).

TL;DR: In this article, it was shown that a type III-like liquid−liquid critical curve already exists within the immiscibility hole and that it can emerge from this hole if metastable states are included.
Abstract: Liquid−liquid miscibility in binary and ternary fluids has been studied to a great extent by Professor Schneider. One of the important results of his studies was the description of the so-called immiscibility holes or islands in type IV systems. In these holes, the liquid−liquid coexistence curve virtually disappears; i.e., it goes below the vapor pressure of the mixture where the liquid becomes metastable to the liquid−vapor phase transition. In the case of the ternary system, the critical end-points then form a closed loop which is the so-called immiscibility hole. Changing, for example, the composition in ternary systems or the molar mass in binary systems containing chain molecules, one can show that a type III-like liquid−liquid critical curve can emerge from this hole. Here we show that this type III-like critical curve already exists within the hole. As a consequence, the liquid−liquid critical curves of type III and IV systems are similar if metastable states are included. The possibility of indir...
