文摘

Isobaric vapor–liquid equilibria (VLE) data of the ternary system methanol + ethanenitrile +1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl) imide ([EMIM][NTf₂]) and methanol + ethanenitrile +1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl) imide ([BMIM][NTf₂]) as well as their binary system methanol + ethanenitrile (MeCN) were obtained using a improved Othmer still at 101.3 kPa. Results indicated that the addition of [EMIM][NTf₂] or [BMIM][NTf₂] can eliminate the azeotropic phenomenon of the binary system of methanol + MeCN when the mole fraction of the ionic liquids reach 0.05. Besides, the measured ternary data were well fitted with the nonrandom two-liquid model.
