| titleOfInvention | Preparation method of a solid titanium catalyst for olefin polymerization |
| abstract | A preparation method of a solid titanium catalyst for olefin polymerization characteristically comprises the steps of: (1) obtaining a magnesium compound solution by dissolving a magnesium halide compound in an oxygen-containing solvent that is a mixed solvent of a cyclic ether and at least one of alcohols; (2) preparing a carrier by primarily reacting the obtained magnesium compound solution witha titanium halide compound at -10-30 DEG C, then raising a temperature or aging so as to obtain particles, and secondly reacting the particles with a titanium halide compound; (3) preparing a catalyst by reacting the carrier with a titanium halide compound and an electron donor of phthalic acid dialkylester having a C9-13 alkyl group; and (4) washing the prepared catalyst with a hydrocarbon solvent at 40-200 DEG C. |
