Glycerol boils at $$ 290^o C $$ with slight decomposition. Impure glycerine can be purified by

ASteam distillation
BSimple distillation
CVacuum distillation
Correct Answer
DExtraction with a solvent

Solution

The liquids which decompose at its boiling point can be purified by vacuum distillation. Glycerol which decomposes at its boiling point (–563K) can be distilled without decomposition at 453K under 12mm Hg pressure.
