Title:
METHOD FOR MANUFACTURING ALKOXY MAGNESIUM AND ALKOXY MAGNESIUM
Document Type and Number:
WIPO Patent Application WO/2019/151483
Kind Code:
A1
Abstract:
Provided is a method for manufacturing alkoxy magnesium by intermittently adding metal magnesium a plurality of times to an alcohol in a reaction system, wherein: among the second and subsequent additions of metal magnesium to the reaction system, at least one addition that adds at least 5% by mass of the total metal magnesium to be added to the reaction system is performed after the generation speed S (liters per minute) of hydrogen produced by reaction with the alcohol resulting from the immediately previous addition of metal magnesium has increased to a maximum value and has then decreased to 45% or less of that maximum value. This method for manufacturing alkoxy magnesium makes it possible to effectively prepare alkoxy magnesium with high density, a decreased proportion of fine particles, and a narrow granularity distribution.
