Procedure

By advancing the reaction in the presence of a peroxide, such as hydrogen peroxide solution, in the reaction system, a decomposition reaction of the peroxide, (H2O2→H2O+1/2O2↑+98.4 kJ when the peroxide is hydrogen peroxide) is induced during the reaction, and contributes to the elevation of the temperature of the reaction system. Thus, not only can the reaction rate be improved, but also the reaction can be completed without using a heating source. For this reason, the reaction temperature is started from room temperature immediately after charging the starting materials and elevated to about 70 to 110° C. due to the heat of hydration caused by sulfuric acid and water, the reaction heat caused by sulfuric acid and aluminum hydroxide, and the heat of decomposition of hydrogen peroxide solution, and then the resultant reaction mixture is maintained or matured at that temperature, and the thus desired aluminum sulfate can be efficiently obtained.
