A METHOD FOR PREPARING A SOLID CATALYST FOR PROPYLENE POLYMERIZATION

摘要

PURPOSE: A manufacturing method of a solid catalyst for propylene polymerization is provided to provide a solid catalyst capable of manufacturing polypropylene with excellent tacticity and high yield while not containing environmentally toxic material. CONSTITUTION: A manufacturing method of a solid catalyst for propylene polymerization comprises: a step of reacting titanium halide compound and dialkoxy magnesium under the presence of organic solvent; a step of reacting a compound in chemical formula 2 as an internal electron donor with the product; and a step of reacting the product with titanium halide compound. In chemical formula 2, R^1 and R^2 is hydrogen or C1-20 linear or branched alkyl group, C3-20 cyclic alkyl or alkenyl, C6-20 aryl, arylalkyl group or alkylaryl group. R^1 and R^2 can form a ring by combining each other, R^3 and R^4 are C1-20 linear or branched alkyl group.
