Explain sublimation technique of purification method of organic compound

Explanation

Definition: On heating some solid substances change from solid to vapour state without passing through liquid state. The purification technique based on the above principle is known as sublimation. Uses: It is used to separate sublimable compounds from non sublimable impurities. Examples: Sublimation technique is used for purification of mixture of calcium sulphate and camphor. Because camphor undergoes sublimation and separated and calcium sulphate settle at bottom without sublimation.
