摘要: Abstract The solubilities of three dibasic carboxylic acids (adipic acid, glutaric and succinic acid) in water, the ionic liquid 1-butyl-3-methyl-imidazolim tetrafluoroborate ([Bmim][BF 4 ]), aqueous [Bmim][BF ] solutions have been measured by a solid-disapperance method. binodal curve water + [Bmim][BF was also determined experimentally from solid–liquid–liquid coexistence temperature up to near upper critical solution temperature. Experimental results showed that each acid-containing binary behaved as simple eutectic system. solid–liquid equilibrium (SLE) data were correlated with NRTL model for these parameters predicted solid-disappearance temperatures ternary mixtures containing within an average absolute deviation 2.0%.
