Zusammenfassung:	The present invention relates to a solid catalyst for propylene polymerization and a method for preparing polypropylene by using the same. The present invention provides a solid catalyst including a carrier produced by reacting dialkoxy magnesium with a metal halide, a titanium halide, an organic electron donor, etc., and a method for preparing polypropylene by using the same. Particularly, among the two organic electron donors used in the present invention, an internal electron donor containing cyclic diester can be used, and thus the solid catalyst presented in the present invention can be applied to various types of propylene polymerization process such as slurry polymerization, bulk polymerization, gas phase polymerization or the like, thereby preparing a propylene resin with high melt-flowability while having excellent high activity and stereoregularity. 본 발명은 프로필렌 중합용 고체촉매 및 이를 이용한 폴리프로필렌 제조 방법 에 대한 것으로써 디알콕시마그네슘을 금속할라이드와의 반응을 통해서 생성된 담체와 티타늄할라이드, 유기전자공여체 등으로 이루어진 고체촉매 및 이를 이용한 폴리프로필렌 제조방법을 제공하는 것이다. 특히 본 발명에 사용하는 2종의 유기전자공여체 중 시클릭디에스테르가 포함된 내부전자공여체를 사용하는 것으로써 본 발명에서 제시하는 고체촉매는 슬러리 중합법, 벌크중합법 또는 기상중합법 등의 다양한 형태의 프로필렌 중합공정에 적용이 가능하며, 높은 활성과 입체규칙성이 우수하면서도 높은 용융흐름성을 갖는 프로필렌 수지를 제조할 수 있다.
