Figure 3. Data for the separation of a 50% (v/v) methanol and 1-propanol mixture under similar conditions with a Vigreux fractionating column that was either non-insulated or insulated with either tubular polyethylene foam or paper towels and aluminum foil, respectively. A) Fractional distillation plots of boiling point versus volume of collected distillate. B) Plots of elapsed time of distillation versus volume of collected distillate
