Abstract
Official abstract text for this publication.
The purpose of the present invention is to provide a spherical or ellipsoidal magnesium alcoholate having a narrow particle size distribution even when the particle size is small. The present invention provides a method for producing a magnesium alcoholate by adding in a portionwise manner to a reaction system and reacting, metallic magnesium, an alcohol, and at least one of a halogen or a halogen atom-containing compound in the reaction system under alcohol reflux, which is a method for producing a magnesium alcoholate characterized in that a mixture of metallic magnesium, an alcohol, and at least one of a halogen or a halogen atom-containing compound is added to the reaction system at each portionwise addition.
First claim
Opening claim text (preview).
The invention claimed is: 1. A magnesium alcoholate which is a particulate matter comprising a particle size distribution represented by (D 90 −D 10 )/D 50 of 1.0 or less and a spherical or ellipsoidal particle shape, wherein the particulate matter is composed of porous aggregates of spherical, ellipsoidal, scale-like or needle-like primary particles of magnesium alcoholate having a particle diameter of 1 to 10 μm. 2. The magnesium alcoholate which is a particulate matter according to claim 1 , wherein the pores presented inside the particulate matter have a pore diameter of 0.1 to 5 μm. 3. The magnesium alcoholate which is a particulate matter according to claim 1 , wherein the particulate matter does not contain secondary particles having a particle diameter of 10 μm or less.
