Title:
METHOD FOR PRODUCING CATALYST
Document Type and Number:
WIPO Patent Application WO/2018/003389
Kind Code:
A1
Abstract:
Provided is a production method for a catalyst, by which a catalyst that is a metallocene compound can be produced with high purity and high yield by using a ligand of a specific structure containing a fluorene skeleton. According to the present invention, a catalyst is produced by a method which comprises: a step (I) wherein a ligand of a specific structure containing a fluorene skeleton is reacted with a specific amount of an organic lithium compound of a specific structure; a step (II) wherein the product of step (I) is reacted with one or more compounds selected from the group consisting of Mg compounds of a predetermined structure, Zn compounds of a predetermined structure and Al compounds of a predetermined structure; and a step (III) wherein the product of step (II) is reacted with at least 1 molar equivalent, with respect to the ligand, of a Ti compound, a Zr compound or an Hf compound, said compound having a halogen atom or the like.
