Method for producing dialkoxymagnesium, solid catalyst component for olefin polymerization, solid catalyst for olefin polymerization, and method for producing olefin polymer

摘要

Problem to be solved: to provide a method of producing a dialkoxymagnesium to obtain a dialkoxymagnesium having a narrow particle size distribution, a small BD and a hard particle.Manufacturing method of dialkoxymagnesiumAs the reaction promoterUsing halogenMagnesium metalAdding to the reaction vessel in multiple timesAt the start of the reaction, the value of the amount of alcohol (M3) in the reaction vessel at the start of reaction is determined as the value of the amount of metal (M3) in the reaction vessel at the start of the reaction.After the addition of the total amount of metal magnesium added to the reaction vessel from the beginning to the final metal magnesium addition operation, the rate (s \/ min) of the hydrogen produced by the reaction after the final metal magnesium addition operation is increased to its maximum value after the final metal magnesium addition operationBy the time it falls to 45% of the maximum valueWhen the value of the total amount of alcohol added to the reaction vessel isThe ratio of B value to a value (B \/ a value) is 2.10 toA method of producing a dialkoxymagnesium characterized by.No selection
