topological transformation

A Generalized Scheme of Topological Transformation of Phase Diagrams of Ternary Delaminating Salt-Binary Solvent Systems with Salting-out

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 for Сut 1 of the Quaternary System Water – Pyridine – Butyric Аcid – Potassium Сhloride

Phase equilibria and critical phenomena in cut 1 of the quaternary system water - pyridine - butyric acid - potassium chloride whose constituent ternary liquid system had a closed binodal curve were studied by means of the visual-polythermal method within 5-80°C. The volumes of two monotectic states in the composition tetrahedron have been found to be in contact via critical tie lines with increasing temperature.

Topological Transformation of the Phase Diagram of the Ternary System Potassium Formate - Water - n.Butoxyethanol

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.

Topological Transformation of Phase Diagrams for Сut 1 of the Quaternary System Potassium Nitrate – Water – Pyridine – Butyric Аcid in 5–60оС

Phase equilibria and critical phenomena in component mixtures of the cut 1 of the quaternary system Potassium Nitrate – Water – Pyridine – Butyric Аcid whose constituent ternary liquid system had a closed binodal curve were studied by means of the visualpolythermal method within 5–60oC. The volumes of two monotectic states in the composition tetrahedron have been found to be in contact via critical tie lines with increasing temperature.
