Many of the organic compounds sublime on heating. This means that, these compounds directly form vapours when solid compounds are heated, without becoming a liquid at any stage. On cooling the vapours, the solid is directly obtained. This principle is made use of for the purification of such organic compounds from nonvolatile impurities.
Naphthalene, anthracene and camphor are a few examples of compounds that are easily purified by sublimation.
