In the product of the ethylene oligomerization reaction in the process of separation and purification, and use this to adjust the temperature of the reaction product to improve the energy efficiency, the separation of ethylene oligomerization reaction method is disclosed. The separation method of the ethylene oligomerization reaction is that in the product of the polymerization of ethylene in the process of separation and purification, the unreacted ethylene and 1-butene in the reaction product only C2 / C4 separation tower, or 1-butene is separated at the same time, C4 is discharged from the separating column is separated cooling the remaining reaction product is supplied to the raw material for the separating column C6; And sikimeuroseo cooled to the cooling the remaining reaction product C6 separating column, solvent separating column, C8 separating column and C10 comprising the sequential transfer step of a separation column, wherein the C2 / C4 separation column or a reaction product discharged from the C4 separation tower heat generated is characterized in that used is supplied to the reboil of the C6 cut column.
