アミン-水-苛性アルカリ系の平衡 (第8報)

Abstract

Mutual solubility of pyridine-water-sodium hydroxide system was measured at 0, 30, 60, and 90°, and their equilibrium diagrams and conjugation curves were obtained. Mutual solubility of pyridine and water is markedly affected by temperature and the presence of caustic alkali. At a definite temperature, the mutual solubility decreases with an increase in the concentration of sodium hydroxide, while the concentration of pyridine in equilibrium with a definite concentration of sodium hydroxide solution increases with the increase of temperature.
