摘要:There is disclosed a process for producing an ethylenic oligomer whichcomprises subjecting ethylene to oligomerization reaction in an organic solvent in thepresence of a Ziegler based catalyst, and recyclingly using for the oligomerizationreaction, the organic solvent separated by distillng the resultant oligomerization reactionproduct, wherein the water concentration in the oligomerization reaction system is atmost 8 ppm by weight, or the concentration of olefins which have at least 3 carbon atomsand which are contained in the organic solvent to be recycled in the oligomerizationreaction system is at most 2% by weight. The process of the present invention canmaintain the catalytic activity of the catalyst at a high level.
