ABSTRACT
Densities of three binary systems, 1-butyl-3-methylimidazolium tetrafluoroborate ([BMIM][BF4]) + ethanol, [BMIM][BF4] + benzene, and [BMIM][BF4] + acetonitrile, over the miscible composition range at T = (313.2 to 473.2) K were measured by means of a densimeter at elevated pressure up to 2.00 MPa. The total uncertainty of density was +- 0.0009 g*cm-3. The experimental densities were correlated by an empirical equation. The total average relative deviation (ARD) was 0.08 %, and then the excess molar volumes, VE, were calculated using the experimental densities. The uncertainty of the excess molar volumes was estimated to be about +- 0.008 cm3*mol-1.
