Novel method for stabilizing sodium hypochlorite disinfectant

Abstract

The invention discloses a novel method for stabilizing the sodium hypochlorite disinfectant. The preparation process using the method mainly relates to a novel sodium hypochlorite stabilizer which may be chlorobromocyclotriphosphazene (ClnBrmN3P3, wherein the sum of n and m is equal to 6, and n is not greater than 3), chloroiodocyclotriphosphazene (ClnImN3P3, wherein the sum of n and m is equal to 6, and n is not greater than 3), mixed chlorine, bromine and iodine substituents of cyclotriphosphazene, or the mixed halogen or other group substituent of cyclotriphosphazene The disinfectant can be stably stored under the condition of a pH value above 9.2 and added with potassium permanganate as the coloring agent. The method is based on the direct action of hypochlorite in the disinfectant, so that the disinfectant has obviously prolonged stability and effective chlorine retention period compared with the similar disinfection products, and not only reduces the corrosivity of sodium hypochlorite and effectively solves the stability problem of the disinfectant of sodium hypochlorite without increasing the cost and reducing the disinfection and sterilization capabilities of the disinfectant of sodium hypochlorite. The disinfectant can be stored for fourteen days at a constant temperature of 54 DEG C and constant humidity and three months at a constant temperature of 37 DEG C and constant humidity, and the reduction of available chlorine is less than 10 percent under the conditions.

Description

technical field [0001] The invention relates to a method for stabilizing a sodium hypochlorite disinfectant, utilizing the interaction between a novel stabilizer and sodium hypochlorite to effectively solve the problem of stabilizing the sodium hypochlorite disinfectant. Background technique [0002] Sodium hypochlorite (NaCl0) is a kind of bleaching agent, disinfectant and deodorant commonly used, and it is characterized in that production process is simple, and cost is low, is widely used in medical sanitation disinfection and industrial and agricultural production, a lot of chlorine-containing disinfectants on domestic and foreign markets Both are compounded with sodium hypochlorite as the main component, and are widely used as detergent builders abroad. However, because sodium hypochlorite aqueous solution has poor stability and is easy to decompose, it brings many difficulties in transportation, storage and use. Due to the fact that industrial sodium hypochlorite itsel...
