Alcohol is dehydrated using _______________________ distillation?
Correct answer: B. Azeotropic
- A. Extractive
- B. Azeotropic
- C. Steam
- D. Molecular
Explanation
Ethanol and water form an azeotrope, so ordinary fractional distillation cannot achieve complete dehydration. An entrainer in azeotropic distillation changes the phase equilibrium and allows further water removal.
