Environmental damage and depletion of resources are concerns, as well as the need for sustainable alternatives. An extractive industry is one that consumes or uses natural raw materials in an […]
[ad_1] Fractional distillation separates volatile compounds based on boiling points, but some blends require extractive distillation. Azeotropes cannot be separated by fractional distillation. Extractive distillation uses a high-boiling solvent to change relative volatilities and separate compounds. The solvent must have a higher boiling point than the less volatile substance and be introduced as a vapor. […]
