_____________ is used as an 'entrainer' for the separation of acetic acid-water mixture by distillation?
Correct answer: C. Butyl acetate
- A. Furfural
- B. Benzol
- C. Butyl acetate
- D. Hexane
Explanation
Butyl acetate is used as an entrainer in azeotropic distillation to facilitate separation of acetic acid and water by altering the mixture's volatility relationships. The entrainer forms a more readily separable azeotropic system.
