Preparing method of solid catalyst for polypropylene polymerization, and solid Catalyst using the method

摘要

This invention relates to a method of manufacturing method, and hence the polypropylene polymer of the solid catalyst for polymerization of polypropylene relates to, in particular (1) reacting a magnesium halide compound and a hydrocarbon solvent and an alcohol, here by the addition of 1,2-phthaloyl dichloride preparing a magnesium compound solution, (2) an aliphatic or alicyclic hydrocarbon The solvent and the aromatic hydrocarbon solvent is mixed and reacted with the magnesium compound solution prepared using a mixed solvent of titanium compounds dispersed, heating to generate a carrier, (3) a carrier, and the generation of titanium compound and an electron donor and The reaction is characterized by including the step of obtaining a solid product. Using the catalyst prepared by this invention can be prepared, having a solid catalyst for polymerization of polypropylene having a high activity and high stereoregularity polypropylene properties.
