Solvent used in extractive distillation___________________?
Correct answer: A. Changes the relative volatility of the original components
- A. Changes the relative volatility of the original components
- B. Should be of high volatility
- C. Should form azeotropes with the original components
- D. All A., B. and C.
Explanation
An extractive-distillation solvent is added to alter the relative volatility of the original components and make their separation easier. It is generally chosen to have low volatility and not to form an unwanted azeotrope, so only A is correct.
