This is an ideal value because it means the experiment was a success and, the amount of solvent recovered was close to the theoretical value. In simple distillation, the area percent of 2-methylpentane was 64.461% and 35.539% cyclohexane. The boiling points of ethanol and 2-propanol had a difference of 5C. Distillation is a method of separating two volatile chemicals on the basis of their differing boiling points. The condenser was then placed on a ring stand using a clamp.
