Catalyst system for olefin trimerizau00e7u00e3o and process of trimerizau00e7u00e3o compounds olefu00ecnicos

摘要

"Trimerizau00e7u00e3o catalyst system for olefin and process of trimerizau00e7u00e3o olefu00ecnicos compounds".The invention relates to a catalyst system for the selective trimerizau00e7u00e3o of olefins, and the system is based on a complex of titanium of the formula (CP - B (R) ~ n ~ ar) TIR ^ 1 ^ ~ 3 ~.In which: CP is a binder of the type ciclopentadienila, optionally substituted, B is a group of connection, based on a single atom selected from group 13 to 16, including the periodic system.The air is an aromatic group, optionally substituted, R is, independently, hydrogen, or a hydrocarbon residue, optionally substituted and optionally containing heterou00e1tomos,Or the groups R and B are connected to each other to form a ring, and N is an integer equal to the valency (B 2), and R ^ 1 ^ are a group of mono anionic and comprises in addition an activator.This catalyst system eliminates the use of toxic chromium compounds.
