PREPARATION METHOD OF A SOLID CATALYST FOR POLYPROPYLENE POLYMERIZATION, AND THE SOLID CATALYST OBTAINED THEREFROM

Document Type and Number:

WIPO Patent Application WO/2011/081407

Kind Code:

A2

Abstract:

The present invention relates to a preparation method of a solid catalyst for polypropylene polymerization, comprising: a) reacting a magnesium halide compound with alcohol and adding a phthalic acid compound to prepare a magnesium compound solution; b) reacting the prepared magnesium compound solution with a mixed solution that contains an aliphatic or aliphatic ring hydrocarbon solvent, an aromatic hydrocarbon solvent and a titanium compound that has been dispersed, and heating the mixture to produce a carrier; and c) reacting the produced carrier with the titanium compound and an electron donor to obtain a solid product. By using such a catalyst prepared according to the present invention, it becomes possible to produce polypropylene having high activity and high apparent density properties.
