Vorschrift

Separately, 2.12 kg of 98% conc. sulfuric acid and 1 liter of water were added to 1 kg of the same aluminum hydroxide as set forth above, and the mixture was heated at 100° C. to form a solution. Then, water was added to form 3 liters of an aqueous solution of aluminum sulfate. The resulting sodium aluminate solution and the resulting aluminum sulfate solution were separately added dropwise over the course of 1 hour to 7 liters of water being stirred, while maintaining the pH of the mixture at 8.5 to 9.0. The reaction mixture was aged for 1 hour, and then, nitric acid was added to the solution to adjust its pH to 6.0. The resulting aluminum hydroxide was filtered, washed with water, and dried at 150° C. to form boehmite-like aluminum oxide monohydrate.
