Method for removing iron impurities in alkoxy aluminum

The invention discloses a method for removing iron impurities in alkoxy aluminum. The method comprises the steps that supporting electrolyte is added in an alcoholic solution of the alkoxy aluminum, an electrolyte is formed by mixing evenly, an aluminum electrode is inserted into the electrolyte as a cathode, an inert electrode is used as an anode, an electrolytic reaction is conducted at the temperature being +/-80 DEG C of the boiling point of an alcoholic solution of the alkoxy aluminum, and a high-purity alcoholic solution of the alkoxy aluminum is obtained after the reaction. According tothe method, an electrolytic method is used for removing the iron impurities in the alkoxy aluminum, operation is easy, and the effect is good.

The state of Al(III) in alcohol solutions of aluminum alkoxide as probed by 27Al and 13C NMR and small-angle X-ray scattering

Solutions of aluminum alkoxides obtained by interaction of aluminum metal with methyl, ethyl, and isopropyl alcohols were studied by 27Al and 13C NMR and small-angle X-ray scattering. Alkoxides with a tetrahedral environment of aluminum prevail in methanol solutions, and those with an octahedral environment of aluminum predominate in ethanol solutions. In isopropyl alcohol at 293 K, polynuclear alkoxides with tetrahedral, octahedral, and pentacoordinated aluminum environments coexist. The structure of polynuclear complexes was refined by comparison of their calculated dimensions with small-angle X-ray scattering data.
