Abstract

The invention discloses a stable peroxyacetic acid solution, a preparation method of the stable peroxyacetic acid solution, and a stabilizer for preparation of the stable peroxyacetic acid solution. The stabilizer comprises a component A and a component B. The component A is a diethylene triamine penta (methylene phosphonic acid) aqueous solution having the concentration of 45 to 55 wt% or an amino trimethylene phosphonic acid aqueous solution having the concentration of 45 to 55 wt% or a mixture of the diethylene triamine penta (methylene phosphonic acid) aqueous solution and the amino trimethylene phosphonic acid aqueous solution. The component B is a sodium hydroxide aqueous solution which has the concentration of 10 to 15 wt% and is added with 50 to 100ppm of complexation components. The stable peroxyacetic acid solution comprises 5 to 25% of peroxyacetic acid, 15 to 25% of hydrogen peroxide, 0.04 to 0.06% of the component A, 0.15 to 0.25% of the component B and the balance water.The stable peroxyacetic acid solution can be stored at a normal temperature for 18 months or more, has good stability, and effectively solves the safety and economy problems of the existing peroxyacetic acid solution. The stable peroxyacetic acid solution has a simple formula, does not contain components of lead, arsenic and sulfates limited by the GB19104-2003 standard, and has environmental benefits.

Description

technical field [0001] The present invention relates to a peracetic acid solution with purposes of sterilization, disinfection and bleaching and a preparation method thereof, and particularly relates to a stabilizer for preparing the peracetic acid solution. Background technique [0002] Peracetic acid is a colorless liquid with a pungent odor. It is a strong oxidant and is easy to decompose. Under the conditions of alkalinity, reducing substances and metal ions, it will react violently, decompose or even explode. Peracetic acid is an excellent organic peroxide, which has a wide range of applications in many aspects. It has high-efficiency and rapid bactericidal effect, and can quickly kill bacteria, spore fungi, yeast and other germs, so it can be used as a treatment for infectious diseases. , drinking water, food and other disinfectants. During the SARS period and the Wenchuan earthquake epidemic prevention period, peracetic acid played a major role. Peracetic acid also ...
