"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.
