Phase Equilibria and Critical Phenomena for Cut 3 of the Qua­ ternary System Water - Pyridine - Butyric Acid - Potassium Chloride

Phase equilibria and critical phenomena in cut 3 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 5-90°C. We have determined the temperature dependence of the solution composition corresponding to the critical solution point of the immis- cibility region.
