Summary: | A catalytic composition effective in the selective hydrogenation of double olefinic links prepared through the reaction between: (A) at least a bi(cyclopentadiene)titanium having general formula (I) (C5H5)2Ti(R)R1), wherein R and R1, equal to or different from each other, are halogens, the aforementioned compound (I) in solid state or in dispersion with one or more non-dissolving diluents; (B) at least an organic derivative comprising generalformula (II) M(R2)R3), wherein M is selected from Zinc and magnesium, preferably magnesium, and R2 and R3, equal to or different from each other, are selected from alkyls of 1 to16 carbon atoms; (C) at least a modifier.
Una composicion catalítica efectiva en la hidrogenacion selectiva de ligaduras dobles olefínicas preparada mediante la reaccion entre: (A) por lo menos un derivado de bis(ciclopentadienil)titanio que tiene la formula general (I) (C5H5)2Ti(R)R1) en donde R y R1, iguales o diferentes, son halogenos; el compuesto anterior (I) en estado solido o disperso en uno o más diluyentes no solventes; (B) por lo menos un derivado orgánico que tiene la formula general (II) M(R2)R3), en donde M se selecciona de zinc y magnesio, de preferencia magnesio, y R2 y R3, iguales o diferentes, seleccionan de alquilos de C1-C16; (C) por lo menos un modificador. |
