Beschreibung
Zusammenfassung:	An apparatus for a simplified purification of organic material by means of an ionic liquid according to the present invention comprises: a sublimation means for sublimating by heating raw organic material, for OLED, containing impurities; a recrystallization means for recrystallizing, in an ionic liquid, sublimated gas from the sublimated organic material; and a control means for controlling the operations of the sublimation means and the recrystallization means. The present invention has the benefit of allowing the purifiability of the organic material to be easily verified with a trace amount thereof as the recrystallization in the ionic liquid can be verified even when a trace amount of the organic material is sublimated.
