| 1. A process for producing a solid catalyst component for olefin polymerization, comprising;
reacting (a3) a halogen-containing titanium compound, (b3) an alkoxy-group-containing magnesium compound obtained by reacting
metal magnesium, 2 to 100 mol of an alcohol per mole of said metal magnesium, and a halogen and/or halogen-containing compound
in a ratio of at least 0.0001 gram atom and less than 0.06 gram atom of halogen atom per mole of said metal magnesium, (c3-1)
a halogen-containing silicon compound in which the molar ratio of halogen to the alkoxy group of the alkoxy-group-containing
magnesium compound (b3) is 0.50 or more, and (d3) an electron-donating compound, or
reacting (a3) a halogen-containing titanium compound, (b3) an alkoxy-group-containing magnesium compound obtained by reacting
metal magnesium, 2 to 100 mol of an alcohol per mole of said metal magnesium, and a halogen and/or halogen-containing compound
in a ratio of at least 0.0001 gram atom and less than 0.06 gram atom of halogen atom per mole of said metal magnesium, and
(c3-1) a halogen-containing silicon compound in which the molar ratio of halogen to the alkoxy group of the alkoxy-group-containing
magnesium compound (b3) is 0.50 or more,
at a temperature of 120° C. or higher but no more than 150° C. to obtain a reaction mixture,
washing the reaction mixture with an inert solvent at a temperature of 100° C. or higher but no more than 150° C.,
further reacting the reaction mixture with (a3) a halogen-containing titanium compound at least once at a temperature of 120°
C. or higher but no more than 150° C. , and
washing the reaction mixture with an inert solvent to obtain a solid catalyst component.
