Flash distillation is suitable for separating the constituents of a binary system, which _____________________?
Correct answer: B. Have very wide boiling points
- A. Form minimum boiling azeotrope
- B. Have very wide boiling points
- C. Have very close boiling points
- D. Form constant boiling azeotrope
Explanation
Flash distillation provides only limited separation in a single equilibrium stage, so it is most useful when the components have substantially different volatilities and hence widely separated boiling points. Components with close boiling points require more efficient fractionation.
