Fractional distillationis a method used for mixtures when the boiling points of the liquids differ by 8-10C. When compared this numbers to the expected value (70% 2-methylpentane, 30% cyclohexane), the experimental data was lower than that. The percent area of 2-methylpentane is higher in fractional distillation than simple distillation, thus fractional distillation separates the product much purer than simple distillation. and is an 0000001469 00000 n

Distillation may result essentially complete separation (nearly pure component), or it may be a partial separation that increases the concentration of selected components of the mixture.
