In case of ______________ distillation, a solvent is added to alter the relative volatility of the mixture to be separated?
Correct answer: A. Extractive
- A. Extractive
- B. Azeotropic
- C. Molecular
- D. Flash
Explanation
Extractive distillation adds a relatively nonvolatile solvent that changes component relative volatilities without necessarily forming a new azeotrope. Azeotropic distillation instead commonly adds an entrainer to alter azeotropic behaviour.
