Method for producing magnesium alcoholate

Abstract

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.

1 . A method for producing a magnesium alcoholate comprising:
 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 a reaction system under alcohol reflux,   wherein 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.   
     
     
         2 . The method for producing a magnesium alcoholate according to  claim 1 , wherein a frequency of portionwise addition of said mixture is less than 10 times. 
     
     
         3 . The method for producing a magnesium alcoholate according to  claim 1 ,
 wherein a mass ratio of metallic magnesium and alcohol and a mass ratio of metallic magnesium and halogen or halogen atom-containing compound in said mixture that is added in a portionwise manner is set to be substantially constant at each portionwise addition.   
     
     
         4 . The method for producing a magnesium alcoholate according to  claim 1 ,
 wherein an interval of portionwise addition of said mixture is set to be substantially constant.   
     
     
         5 . The method for producing a magnesium alcoholate according to  claim 1 ,
 wherein the halogen or the halogen-containing compound is reacted in an amount of 0.0001 gram atom or more, relative to one gram atom of the metallic magnesium.
