| 摘 要： | Introduction The salting out effect in the systems of aliphatic al-cohol-water is of industrial interest. The addition of or-ganic solvents to the aqueous solution of a salt normally decreases the solubility of the salt. So the method can be used for salting-out of inorganic salts to improve yield and purity.1-3 However, the phase diagrams of the inves-tigated systems are required as basic data. There are lots of aliphatic alcohol-water systems having been deter-mined. The 1-butanol-water-Na…

| Abstract: | The phase diagrams of the CH3CH2OH‐Cs2CO3‐H2O 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 Cs2CO3. 3.5H2O. The refractive index of the systems was also determined. |
