| titleOfInvention | CATALYTIC COMPOSITION FOR THE OLIGOMERIZATION OF ETHYLENE THAT INCLUDES TITANIUM MONOCICLOPENTADIENYL COMPOUNDS. |
| abstract | Catalytic composition that can be used in the selective trimerization of ethylene to 1-hexene, which comprises the reaction product of: a) a titanium monocyclopentadienyl compound having the following formula (I): [ATiRn] m in which: Ti it is a titanium atom in an oxidation state of +3 or, preferably, +4; A is an anion that contains a η 5 -cyclopentadienyl ring coordinated to the titanium atom; each R independently represents a covalently linked group with σ bonds to the titanium atom, selected from hydride, halide, a C1-C8 alkyl group, a C3-C12 alkylsilyl group, a C5-C8 cycloalkyl group, a C6-C10 aryl group , a C1-C8 alkoxy group, a C1-C30 carboxyl group, a C2-C10 dialkylamide group; "n" is equal to 2 or 3 when the titanium is in a +3 or +4 oxidation state, respectively; "m" is an integer between 1 and 4; b) a non-monomeric aluminum oxyhydrocarbyl compound, and c) an organometallic hydrocarbyl compound selected from among compounds having the following formula (III): wherein M is Al, (I) (R ') m M Xs - m (III) R 'is a hydrocarbyl group having from 1 to 15 carbon atoms, X is chlorine or bromine, m is an integer between 1 and s, preferably s, s is the valence of metal Al and has the value of 3, according to the chemical nature of Al, characterized in that it is obtained by means of a process comprising the following consecutive steps: i) putting said titanium complex (a) in contact and reacting it, in a suitable inert liquid medium, with a amount of said aluminum oxyhydrocarbyl compound (b), so that the Al / Ti atomic ratio is between 50 and |
