preparation example Construction

[0014] The preparation method of the disinfectant of the present invention comprises the following steps: adopting the chlorite method to prepare chlorine dioxide, adding excessive chlorite when preparing raw materials so that the concentration of chlorite in the disinfectant is at least 0.0148mol / L; or Chlorite is added to the solution obtained by absorbing chlorine dioxide gas with an aqueous solution, so that the concentration of chlorite in the solution is at least 0.0148 mol / L.

[0015] Wherein, the chlorite is one or both of sodium chlorite and potassium chlorite. Because of using sodium chlorite and potassium chlorite as raw material, the product quality is the same, but the cost of sodium chlorite is the lowest, so sodium chlorite is preferred.

[0016] Specifically, disinfectant of the present invention can adopt following method preparation:

[0017] Method 1. Use chlorite as raw material: Calculate the amount of raw material according to the required concentration ...

Embodiment 1

[0025] The preparation of embodiment 1 disinfectant of the present invention

[0026] Prepare the disinfectant whose chlorine dioxide concentration is 100ppm / L and chlorite content is 0.0148mol / L. Add 2 grams of sodium chlorite, 0.6 grams of dodecyldimethylbenzyl ammonium chloride, and 0.4 grams of trimethylsiloxane into 1000 grams of water, and then add 0.1 grams of citric acid after completely dissolving and mixing uniformly. After reacting for 15-20 minutes, store it in a dark, cool and airtight container.

Embodiment 2

[0027] The preparation of embodiment 2 disinfectants of the present invention

[0028] Prepare the disinfectant whose concentration of chlorine dioxide is 100ppm / L and the content of chlorite is 0.074mol / L. In 1000 grams of water, add 6 grams of sodium chlorite, 6 grams of dodecyldimethylbenzyl ammonium chloride, and 4 grams of trimethylsiloxane. After completely dissolving and mixing uniformly, add 0.054 grams of hydrochloric acid to react. After 15-20 minutes, store it in a dark, cool and airtight container.

Abstract

The invention relates to a disinfectant, which belongs to the disinfectant field, wherein, the disinfectant contains chlorine dioxide, and the concentration of chlorite is at least 0.0148mol / L. The disinfectant can be stored for three months to one year, and the concentration of chlorine dioxide in the disinfectant can be maintained in storage period, and the chlorine dioxide solution ca be used at any moment without the need to prepare it in site.

Description

technical field [0001] The invention relates to a disinfectant which uses chlorine dioxide for disinfection and belongs to the field of disinfectants. Background technique [0002] Chlorine dioxide is a broad-spectrum powerful bactericidal disinfectant, high-efficiency oxidant and excellent bleaching agent. It is widely used in countries all over the world. The World Health Organization has designated it as an AI-level high-efficiency and safe disinfectant. Widely used in medical and health, disinfection and sterilization, deodorization and deodorization, food preservation, water purification, bleaching and other fields. [0003] At present, the use of sodium chlorite to prepare chlorine dioxide is to use sodium chlorite as a raw material to react with acidic substances such as excessive hydrochloric acid to generate chlorine dioxide. The pH value of the chlorine dioxide solution prepared by detecting this method is less than 3. The chlorine dioxide solution prepared by the...
