Abstract:
A process for the oligomerization of C3- to C5-olefins proceeds in the presence of a catalyst, wherein the oligomerization is carried out in at least one reaction stage which includes at least one reactor and at least one distillation column. The content of oligomers in the feed stream to the at least one reaction stage after removal of the oligomers in the at least one distillation column is less than 0.4% by weight.
