ETHYLENE OLIGOMERIZATION PROCESSES

Disclosed herein is a process for forming an oligomer product comprising (a) introducing into a reaction zone (i) ethylene; (ii) a heteroatomic ligand metal salt complex comprising a heteroatomic ligand complexed to a first metal salt; (iii) a second metal salt wherein an equivalent molar ratio of the second metal salt to the heteroatomic ligand of the heteroatomic ligand metal salt complex is atleast 0.5: 1 and where the second metal salt is an iron salt, a cobalt salt, or any combination thereof; (iv) an organoaluminum compound; and (b) forming an oligomer product. Also disclosed herein isa process comprising (a) introducing into a reaction zone (i) ethylene; (ii) heteroatomic ligand; (iii) a metal salt where an equivalent molar ratio of the metal salt to the heteroatomic ligand is atleast 1.5: 1; (iv) an organoaluminum compound; and (b) forming an oligomer product.
