Liquid-Liquid Coexistence Curves of {x 1-Butyl-3-methylimidazolium Tetrafluoroborate + (1 - x) 1,3-Propanediol} and {x 1-Butyl-3-methylimidazolium Tetrafluoroborate + (1 - x) 1,4-Butanediol}
The liquid-liquid coexistence curves of the binary solutions of 1-butyl-3-methylimidazolium tetrafluoroborate ([C4mim][BF4]) + 1,3-propanediol and [C4mim][BF4] + 1,4-butanediol were determined by measuring the temperature dependence of the refractive index in the two phases of the samples with critical compositions. The critical amplitude B and the critical exponent ? have been deduced from the coexistence curves. The experimental values of ? are consistent with theoretical prediction. The results have also been analyzed to determine the Wegner-correction terms and to examine the asymmetric behavior of the diameters of the coexistence curves.
