Liquid–liquid equilibria for some aliphatic alcohols + cesium carbonate + water systems

Liquid–liquid phase equilibrium was determined at 298.15 K for some aliphatic alcohols + cesium carbonate + water systems. The alcohols used were methanol, ethanol, 1-propanol and 2-propanol. Measurement of 1-propanol + cesium carbonate + water system was also made at 308.15 and 318.15 K. The binodal curves were correlated using a five-parameter equation and tie lines were correlated with the Othmer–Tobias and Bancroft equations. The refractive index of the liquid phase was also determined.
