Abstract
Isobaric vapor–liquid equilibrium (VLE) data for the binary system methanol + dimethyl carbonate as well as the VLE data for the ternary systems methanol + dimethyl carbonate +1-ethyl-3-methylimidazolium trifluoromethanesulfonate ([EMIM][OTf]) and methanol + dimethyl carbonate + 1-butyl-3-methylimidazolium trifluoromethanesulfonate ([BMIM][OTf]) at 101.3 kPa have been obtained with a modified Othmer still. The results indicated that both [EMIM][OTf] and [BMIM][OTf] produced crossover effects. Due to the difference of polarity of the two ILs, [BMIM][OTf] eliminated the azeotropic point at mole fraction about 10%, whereas [EMIM][OTf] only pulled down the azeotropic point. The measured VLE data were fitted using the NRTL model with a good consistency.
