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. (c) 2007 Elsevier B.V. All rights reserved.
