The phase diagrams of the CH 3 CH 2 OH‐Cs 2 CO 3 ‐H 2 O system were determined at 10, 30 and 50 C, respectively. It was found that the effect of the temperature on the phase equilibrium was insignificant within the investigated range. The binodal curves were given using a five‐parameter equation and the tie lines were fitted using the Oth‐mer‐Tobias and Bancroft correlations. Correlation coefficients ( R ) for all equations exceeded 0.99. Samples of the solid phase at 30 °C were analyzed by TGA showing that it consisted of Cs 2 CO 3 . 3.5H 2 O. The refractive index of the systems was also determined.
