MAGNESIUM HALIDE SOLUTION, PREPARING METHOD AND USE THEREOF

摘要

The present invention provides a magnesium halide solution; the magnesium halide solution contains a magnesium halide, an oxygen-containing organotitanium compound, a hydroxyl-containing compound, and an organic solvent; furthermore, the magnesium halide solution also comprises an organic heterocyclic compound, said organic solvent being a hydrocarbon compound and/or a halogenated hydrocarbon compound. The organic heterocyclic compound is selected from at least one of an organic sulfur-containing heterocyclic compound, an organic nitrogen-containing heterocyclic compound, and an organic epoxy compound. The amorphous magnesium halide solution provided by the present invention has good stability, can be used for preparation of olefin polymerization and copolymerization catalysts, and has the advantages of inexpensive and readily available starting materials, a convenient method of preparation, and environmental friendliness.
