Apparatus for purifying organic compound and method of purifying organic compound

An apparatus for purifying an organic compound, the apparatus comprising:

• an inner tube that receives a purification target material therein;
• a heater that heats the purification target material received in the inner tube;
• an evacuator that evacuates the inner tube into a vacuum;
• and
• a driving device that drives the inner tube,
• wherein the inner tube includes:
• a supply unit to which the purification target material is supplied;
• and
• a collecting unit in which the purification target material is sublimated or liquefied as it moves toward the evacuator,
• wherein the driving device includes:
• a drive unit that generates power;
• and
• a power transmission unit that transmits the power generated by the drive unit to the supply unit to move the supply unit,
• wherein the power transmission unit includes:
• a power transmission member that receives power from the drive unit;
• and
• a supply unit-holding member that transmits power received in cooperation with the power transmission member to the supply unit, and
• wherein the supply unit-holding member includes:
• an outward holding portion that extends to surround an outer surface of the supply unit;
• and
• a longitudinal holding portion that extends in a longitudinal direction of the supply unit and intersects the outward holding portion.
