PURPOSE: To obtain an aqueous peracetic acid solution useful for a breaching agent for nylon fabrics, etc., a bactericide, an epoxidating agent, etc., without using an aqueous hydrogen peroxide solution of a high concentration and at an industrially low cost by reacting a specific amount of acetic anhydride with the aqueous hydrogen peroxide solution. CONSTITUTION: This method for producing an aqueous peracetic acid solution comprises reacting (A) an aqueous hydrogen peroxide solution with (B) acetic anhydride with an amount of a lower molarity than that of water. Furthermore, preferably the concentration of the component (A) is 50-70wt.%, and the reaction is carried out by adding the component (B) into a reaction vessel containing the component (A) and using 0.2-2.0wt. % acid catalyst such as sulfuric acid or phosphoric acid and 0.01-2.0wt.% metallic ion sequestering agent such as an aminocarboxylic acid as a stabilizer based on the total amount of the reaction mixture at 0-90 deg.C, especially 10-50 deg.C. |
