Patent

CA 2020509

Novel chromlum-containing compounds, such as, for example, chromium pyrrolides, are prepared by forming a mixture of a chromium salt, a metal amide, and an electron pair donor solvent, such as, for example, an ether. These novel chromium-containing, or chromium pyrrolide, compounds can be used either unsupported or supported on an inorganic oxide support to trimerize and/or polymerize olefins.

De nouveaux composés contenant du chrome, par exemple, des pyrrolides de chrome, sont préparés en formant un mélange d'un sel de chrome, d'un amide de métal et d'un solvant donneur d'une paire d'électrons comme, par exemple, un éther. Ces nouveaux composés contenant du chrome, ou pyrrolide de chrome, peuvent être utilisés avec ou sans support sur un support d'oxyde inorganique pour trimériser et/ou polymériser des oléfines.
