Measurement and correlation of isobaric vapor-liquid equilibria of methanol + tetrahydrofuran + 1-alkyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide at 101.3 kPa

We investigated the isobaric vapor-liquid equilibria (VLE) of the binary system methanol + tetrahydrofuran (THF), the ternary system methanol + THF + 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([BMIM][NTf2]), as well as methanol + THF + 1-hexyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([HMIM][NTf2]) in a modified Othmer still. The results indicated that the ionic liquids ([BMIM][NTf2] and [HMIM][NTf2]) produced a...
