<p>The present invention relates to a method and an apparatus for purifying organic materials using ionic liquid. It includes a step of mixing an organic material with ionic liquid, a step of melting the organic material mixed with the ionic liquid in a first condition, a crystallization step of crystallizing the molten organic material in a second condition, and a step of separating the crystallized organic material from the ionic liquid. According to the present invention, a high-purity organic material can be effectively purified at low cost by a simply process. A large amount of organic material can be purified with high yield in a relatively short time. The design and control of a purification process can be easily carried out. It can be applied to various organic materials.</p> |
