Problems solved by technology

But this kind of stability has its own disadvantages, because boron nitride is easy to decompose when the pH value is low, thus causing the decomposition of sodium hypochlorite, so this kind of stabilization can only be maintained at a higher pH value
[0015] The above-mentioned methods have changed the motion law of sodium hypochlorite in aqueous solution to varying degrees, but all have their advantages and disadvantages, and there are certain limitations in practice; let alone adding potassium permanganate as a coloring agent to preserve and use at low pH values These have greatly limited the scope of use of this cheap and easy-to-produce disinfectant

Embodiment Construction

[0029] Dilute the sodium hypochlorite stock solution with pure water or distilled water to about 0.5% of available chlorine, add complexing agent EDTA, silicate and borax, and adjust the pH value to about 9.7 with phosphate, add anionic surfactant and stabilizer cyclotriphosphorus Nitrile, stir to dissolve. Add the coloring agent potassium permanganate 1mg / L, canned it in an oxidation-resistant opaque bottle, and stored it in a cool condition. Store at 54°C for 14 days at constant temperature and humidity, and then measure the available chlorine content.

Abstract

A process for stabilizing the disinfecting liquid prepared from sodium hypochlorite and decreasing its corrosion features use of a novel stabilizer, which is the mixture of chlorobromo cyclotriphosphonitrile or chloroiodo cyclotriphosphonitrile or cyclotriphosphonitrile (or the halogen of cyclotriphosphonitrile) and chlorobromoiodine.

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 (NaClO) is a kind of commonly used bleaching agent, disinfectant and deodorant. It is characterized by simple production process and low cost. It is widely used in medical sanitation disinfection and industrial and agricultural production. Many chlorine-containing disinfectants on the 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 itself has certain...
