Document Type and Number:

WIPO Patent Application WO/2006/115040

Kind Code:

A1

Abstract:

A magnesium compound produced through reaction at 0 to 70&ring C of metallic magnesium, ethanol, a C₃-C₁₀ alcohol and a halogen and/or halogenated compound containing a halogen atom in an amount of 0.0001 gram-atom or more per gram-atom of metallic magnesium, which magnesium compound has a composition of the following general formula (I) and has a particle diameter corresponding to 50% cumulative weight percentage, D₅₀, of 4 to 20 μm and a particle diameter distribution index (P) satisfying the relationship P<4.0. Mg(OC₂H₅)_2-n(OR¹)_n (I) wherein n satisfies the relationship 01 is C_mH_2m+1 in which m is an integer of 3 to 10.
