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 a space velocity 5 to obtain an aqueous basic aluminum acetate solution. The obtained aqueous solution was dried at 140° C. and atmospheric pressure to adjust the water content to be 15% to obtain a basic aluminum acetate solid. An absorbance ratio T1 of the basic aluminum acetate, measured by the infrared absorptiometry the above-mentioned evaluation method, was 1.75.
