| 摘 要： | Vapor pressures were measured for acetonitrile+1-butyl-3-methylimidazolium chloride (C4mim]Cl]),+1-butyl-3-methylimidazolium tetrafluoroborate (C4mim]BF4]) and+1-hexyl-3-methylimidazolium chloride (C6mim]Cl]) at temperatures of 313 to 353 K by a quasi-static method. The experimental data for the binary sys-tems were correlated by the non-random two liquid (NRTL) equation with an average absolute relative deviation (AARD) of within 1.84%. The results indicate that the three ionic liquids (ILs) can result in a negative deviation from the Raoult's law for the binary solutions containing acetonitrile, and the affinity between ILs and acetonitrile mole-cules fol ows the order C4mim]BF4]+acetonitrile N C4mim]Cl]+acetonitrile N C6mim]Cl]+acetonitrile.
