实验步骤: 1500 g (14 mol) of sodium hypophosphite monohydrate and 35 g of concentrated sulfuric acid are dissolved in 7.5 kg of water and initially charged in a 16 l steel-enamel jacketed pressure reactor. After heating the reaction mixture to 100° C., a reducing valve set to 6 bar is used to introduce ethylene into the reactor up to saturation. While stirring constantly at an ethylene pressure of 3 bar and a temperature of about 100° C., a solution of 80 g (5 mol %) of hydrogen peroxide (33% by weight) in 300 g of water is metered in homogeneously. At a conversion of ethylene of 90%, the metered addition of hydrogen peroxide is stopped and the reactor is decompressed. After cooling to about 90° C., 746 g (4.67 mol of aluminum) of aluminum acetate in 2254 g of water are added within 60 minutes. Subsequently, the resulting solid is filtered off, washed with 2 l of hot water and dried at 130° C. under reduced pressure. The resulting mixture comprises diethylphosphinic acid aluminum(III) salt and ethylphosphonous acid aluminum(III) salt in a ratio of 88.6% by weight of diethylphosphinic acid aluminum(III) salt and 11.4% by weight of ethylphosphonous acid aluminum(III) salt (92.6% yield). a reducing valve set to 6 bar a temperature of about 100° C. After cooling to about 90° C. Subsequently, the resulting solid is filtered off washed with 2 l of hot water dried at 130° C. under reduced pressure

实验步骤: An aqueous basic aluminum chloride solution of concentration of 5.0% by weight on the basis of Al2O3 was produced by diluting commercialized aqueous basic aluminum chloride solution (23.5% by weight on the basis of Al2O3, 8.15% by weight of chloride ion, 83.3% of basicity, and pH 4.0) with pure water. The aqueous solution was passed through an acetate-type anion exchange resin column at space velocity 5 to obtain an aqueous basic aluminum acetate solution. The obtained aqueous solution was mixed with aluminum borate in proper amount for adjusting the boron atom at 1200 ppm to the aluminum atom in the aqueous solution. The obtained solution was dried at 140° C. and atmospheric pressure to adjust the water content to be 3% to obtain basic aluminum acetate solid. The boron atom concentration was 1200 ppm to the aluminum atom in the obtained basic aluminum acetate. by diluting
