Abstract
Abstract Isothermal phase diagrams of ternary systems fullerenol-d–LaCl3–H2O and fullerenol-d–GdCl3–H2O at 25°C are studied via saturation technique. Solubility diagrams are found to be of a simple eutonic type and are characterized by the salting-out of chloride upon adding fullerenol-d, and short branches of LaCl3 · 7H2O and GdCl3 · 6H2O crystallization, where the salting-in effect is observed.
