WebApr 1, 2024 · Cyclohexane/cyclohexene separation Liquid-liquid extraction Ionic liquids NRTL model 1. Introduction The separation of olefins from paraffins by distillation process involves both large energetic costs and capital investment due to the close relative volatilities of these compounds [1]. WebIntroduction : The purpose of this experiment is to separate a sample of cyclohexane and toluene of unknown proportions using fractional distillation. The two components of the mixture are able to be separated because toluene’s boiling point is 30˚C higher than cyclohexane’s boiling point. Cyclohexane should boil and distil before toluene.
