The present invention relates to a method for preparing a solid catalyst for producing polypropylene, a method for preparing a solid catalyst comprising a carrier, titanium halide, organic electron donor, etc., produced by reacting dialkoxy magnesium with a metal halide, and a method for producing polypropylene using the same To provide. In particular, by using the internal electron donor containing succinimide group among the two organic electron donors used in the present invention, the solid catalyst system proposed in the present invention may be various forms such as slurry polymerization, bulk polymerization or vapor phase polymerization. It can be applied to the propylene polymerization process of propylene resin can be produced excellent in high activity and stereoregularity. |
