An experimental study on the isobaric vapor–liquid equilibria for the ternary system of acetone + methanol + 1-methyl-3-octylimidazolium thiocyanate ([Omim][SCN]) as well as the two acetone + ionic liquid (IL) and methanol + IL binary systems was performed at 100 kPa using a recirculating still (VLE 602 Fischer apparatus). A low IL mole fraction of 0.027 was found to be sufficient break the azeotrope due to the high and specific interactions with acetone and methanol. The nonrandom two-liquid model was used to represent the experimental data. The results are compared with those in the literature for the same mixed solvent system using other ILs.
