Question

Which of the following organic purification methods is specifically and explicitly indicated for liquids that possess very high boiling points and undergo chemical decomposition if heated to their normal boiling points at atmospheric pressure?

Prashant Kotian · Accepted Answer

Correct answer: C. Distillation under reduced pressure (vacuum distillation) lowers the pressure above the liquid, allowing it to boil at a temperature significantly below its normal decomposition point. The classic industrial example is the recovery of glycerol from spent lye.
