When the mixture to be distilled has a very high boiling point and the product material is heat sensitive, the separation technique to be used is _______________ distillation?
Correct answer: B. Steam
- A. Continuous
- B. Steam
- C. Azeotropic
- D. None of these
Explanation
Steam distillation is suitable for high-boiling, heat-sensitive materials because steam lowers the mixture’s boiling temperature, allowing vaporisation below the normal boiling point of the material. This reduces thermal degradation compared with ordinary distillation.
