Provided is a method of recovering unreacted ethylene in an ethylene oligomerization process and reusing the ethylene as a raw material, and more particularly, to a method of recovering unreacted ethylene with an increased recovery rate of reuse. When the method of the present invention is used, most of unreacted ethylene may be dissolved in a solvent to be recovered without loss, and a low boiling point reaction product which is not dissolved in the solvent is removed to prevent an unreacted product from being concentrated in a reactor.
