    摘要: A magnesium compound obtained by reacting metallic magnesium having a sphericity (S) of less than 4.00, the sphericity (S) being represented by the following formula (I), an alcohol, and a halogen and/or a halogen-containing compound containing halogen atoms in an amount of 0.0001 gram atom or more relative to one gram atom of the metallic magnesium, S = (L 1 /L 2 ) 3    wherein L 1 represents the maximum diameter of projection views of metallic magnesium determined by photographing with a scanning electron microscope and thereafter an image processing, and L 2 represents a diameter of a circle having an area equal to the area of the projection view of metallic magnesium. A solid catalyst component is obtained from the magnesium compound and a titanium compound, and a catalyst for olefin polymerization is obtained using the solid catalyst component.

    摘要: A process for quickly preparing easily separable solutions of lithium tertiary-alkoxides. Comprising the steps of reacting lithium metal in bulk form, containing less than 0.6 % by weight of sodium, with a tertiary alcohol in mole ratios of metal to alcohol ranging from 1 to 1 to 10 to 1 in a solvent selected from ethereal or hydrocarbon solvents under an inert atmosphere at elevated temperature for 1 to 10 hours, cooling the product and separating the product solution from the unreacted lithium metal in the reactor, and optionally adding solvent and sufficient lithium metal and alcohol to said unreacted metal in said reactor to maintain said mole ratio of lithium metal to alcohol, and continuing the reaction, thereby to form further lithium tert-alkoxide, and repeating said steps a number of times.
