Estimating the term…
A catalyst which is able to express a high oligomerizing activity of ethylene and a method for the production of α-olefin where ethylene is oligomerized using said catalyst are provided. The present invention relates to a catalyst for the production of α-olefin obtained by contacting (a) clay, clay mineral or ion-exchange layer compound with (b-1) a transition metal complex of Groups 4 to 6 of the Periodic Table and also relates to a method for the production of α-olefin by oligomerization of ethylene using said catalyst. The present invention further relates to a catalyst for the production of α-olefin obtained by contacting (a) clay, clay mineral or ion-exchange layer compound with (b-2) a transition metal complex of Groups 8 to 10 of the Periodic Table and also relates to a method of the production of α-olefin by oligomerization of ethylene using said catalyst.
A catalyst obtained by contacting (a) a clay, a clay mineral or an ion-exchange layer compound with (b-2) a transition metal complex of Groups 8 to 10 of the Periodic Table, wherein the clay, the clay mineral or the ion-exchange layer compound is treated with an organosilane in the presence of water.
