phase diagrams

A generalized scheme of topological transformation of the phase diagrams of ternary delaminating salt – binary solvent systems with salting-out at changing temperature and under constant pressure has been developed for the cases of the binary liquid constituent system being delaminating with an UCST, LCST, or not delaminating over the whole temperature range of its li

Phase equilibria and critical phenomena in the ternary system potas­ sium formate - water - n.butoxyethanol, where a constituent binary liquid system is characterized by phase separation with a closed delamination region, were studied by means of the visual-polythermal method within 25-170°C. The temperature dependences of the com­ positions of the mixtures corresponding to the critical solubility points in the delamination region were determined.
