The conclusion about the homogeneity of the distillate in the fractional distillation of cyclohexane-toluene mixture should be determined. Concept introduction: The fractional distillation is a technique that is used to separate various components or fractions from a mixture on the basis of their volatilities. The fractional distillation can be used if the boiling point difference between the components is less than 75 ° C . Fractional distillation is better than the simple distillation due to the low boiling point range. It is used to separate useful substances from crude oil in oil refineries. A mixture with uniform composition and properties throughout is called homogenous mixture.
