Resumen
Separación de ciclohexano/ciclohexeno mediante destilación extractiva empleando líquidos iónicos
In this work, the suitability of two tetrathiocyanatocobaltate-based ionic liquids, namely bis(1-ethyl-3-
methylimidazolium) tetrathiocyanatocobaltate ([emim]2[Co(SCN)4]) and bis(1-butyl-3-
methylimidazolium) tetrathiocyanatocobaltate ([bmim]2[Co(SCN)4]), and two bis(trifluoromethylsulfo
nyl)imide-based ionic liquids, namely 1-ethyl-4-methylpyridinium bis(trifluoromethylsulfonyl)imide
([4empy][Tf2N]) and 1-butyl-4-methylpyridinium bis(trifluoromethylsulfonyl)imide ([4bmpy][Tf2N]),
as mass separating agents to separate cyclohexane and cyclohexene mixtures by homogeneous extractive
distillation was analysed.
