<p>A vertical refining method of an organic material using an ionic liquid comprises a sublimation step (S110) sublimating an organic material containing impurities; a collecting step (S120) of collecting a sublimation gas by contacting the ionic liquid flowing with the sublimation gas of the organic material; and a recrystallization step (S130) generating a recrystallized organic material by oversaturating the organic material which is a refining target among the sublimation gas dissolved by being collected in the ionic liquid in advance, wherein the ionic liquid flows along the surface of multiple blades arranged in the same angles around a vertical axis. The method in the present invention does not need a process of inverse-sublimation by transferring the sublimation gas generated in the sublimation step, thereby having an advantage of basically preventing contamination of a refined sample caused by an inactive transfer gas used in an existing sublimation refining method.</p> |
