Paragraph 0035-0037; 0050-0051; 0054-0059, (2021/12/07)
The invention provides a preparation method of high-purity alkoxy aluminum. The preparation method comprises the steps that in the presence of activated aluminum, high-purity aluminum and C3-C6 fatty alcohol react at the temperature not higher than the boiling point of the alcohol according to the molar ratio of 1: 3-5, the high-purity alkoxy aluminum is obtained, the mass ratio of the activated aluminum to the high-purity aluminum is 1-10%, the activated aluminum is aluminum left after low-purity aluminum and C3-C6 fatty alcohol are fully reacted at the temperature not higher than the boiling point of alcohol according to the molar ratio of 1: (1.5-2.9), the purity of the low-purity aluminum is not larger than 99.90% by mass, and the purity of the high-purity aluminum is not smaller than 99.99% by mass. According to the method, the reaction time of the fatty alcohol and the metal aluminum can be effectively shortened, and other impurities except impurities carried by the metal aluminum are not introduced.

Paragraph 0038-0040; 0049; 0050, (2019/11/20)
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.
