摘要 |
<p>A magnesium compound obtainable by reacting metal magnesium, ethanol, an alcohol having from 3 to 10 carbon atoms and a halogen and/or a halogen-containing compound containing at least 0.0001 gram atom of a halogen atom relative to one gram atom of the metal magnesium at 0 to 70°C, which comprises composition represented by the formula (I), and which has a particle diameter D 50 corresponding to 50% of cumulative weight fraction of from 4 to 20 µm and a particle size distribution index (P) of P<4.0:
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒMg(OC 2 H 5 ) 2-n (OR 1 ) n €ƒ€ƒ€ƒ€ƒ€ƒ(I)
where n is a numerical value satisfying 0<n<0.35, R 1 is C m H 2m+1 , and m is an integer of from 3 to 10.</p> |
