| Abstract: | Liquid–liquid equilibria data of the Bmim]BF4 + fructose + water system were determined at 298.15, 308.15, 31815 K. It was found that the liquid–liquid equilibria can be formed over a wide component range and the effect of the temperature on the phase equilibria is obvious within the fructose concentration changing from 3 to 40%. The binodal curves were correlated using a five-parameter equation, and the tie lines were fitted the Othmer–Tobias and Bancroft correlations. Correlation coefficients for the equations exceeded 0.99. |
