Dichloro-s-triazine-2,4,6-(1H,3H,5H)-trione sodium salt - Reference Information
| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| chlorine-containing disinfectant | sodium dichloroisocyanurate, bleaching powder, and sodium 2. hypochlorite are several chlorine-containing disinfectants commonly used in my country. The disinfection ability of chlorine-containing disinfectants mainly depends on the content of available chlorine. The higher the content of available chlorine, the stronger the disinfection ability. Chlorine-containing disinfectants are dissolved in water to form hypochlorous acid, which produces bactericidal effect. The amount of hypochlorous acid formed by bleaching powder and triad in solution is related to pH. The lower the pH, the more hypochlorous acid is formed. Sodium dichloroisocyanurate has a higher hydrolysis constant and stronger bactericidal ability than most other chloramine disinfectants. Compared with hypochlorite disinfectants, at low concentrations, sodium dichloroisocyanurate has a slower effect; at high concentrations, because its solution can remain weakly acidic, the bactericidal effect is sometimes even better than hypochlorite. The above chlorine-containing disinfectants have a wide bactericidal spectrum and have a killing effect on bacterial propagules, viruses, fungal spores and bacterial spores. sodium dichloroisocyanurate, also known as youchlorine, is one of the disinfectants of chlorinated isocyanuric acid. similar varieties include chlorobromoisocyanic acid, trichloroisocyanuric acid, dichloroisocyanuric acid, potassium dichloroisocyanuric acid, etc. This product and other chlorinated isocyanuric acid disinfectants have a wide sterilization spectrum, and have a strong killing effect on bacterial propagules, viruses, fungal spores and bacterial spores. It has a strong killing effect on various bacteria (such as Escherichia coli, Staphylococcus aureus, etc.), viruses (such as hepatitis virus), bacterial spores (such as Bacillus subtilis black variant spores) and fungi. Under the action of effective concentration, more than 99.9% of Escherichia coli can be killed in 30 minutes, all bacterial spores can be killed in 5-30 minutes, and all hepatitis viruses can be killed in 5 minutes. This product also has the effect of destroying hepatitis B surface antigen. The effect of sodium dichloroisocyanurate is enhanced in acidic environment, and the lower the pH, the stronger the effect. This product has good stability and no carcinogenic effect. It can be used for disinfection of water and food factory processing utensils and tableware, food, vehicles, livestock and poultry houses, silkworm rooms, fish ponds, utensils, etc. |
| application | sodium dichloroisocyanurate can be applied to disinfection of drinking water and tableware; it can also be used to disinfect the appearance of fruits and eggs to prolong the shelf life; it is widely used in large-scale disinfection of flood fighting and disaster relief, and prevention and disinfection of epidemic infectious disease areas; it can be used in the form of fumigation, water and powder for silkworm farms and silkworm farmers to disinfect silkworm rooms, silkworm tools and silkworm bodies; it can effectively prevent and control fish diseases caused by bacteria, fungi and algae, and also has obvious effects on fish viral diseases; using a 2-3% aqueous solution of chlorine and adding other additives to soak wool or wool blended fibers and fabrics, Can make wool and its products non-pilling and non-pelt, and meet the super washable standards issued by the International Wool Bureau. |
| preparation | (1) dichloroisocyanuric acid neutralization method (chlorination method) cyanuric acid and caustic soda are prepared into an aqueous solution according to a molar ratio of 1:2, chlorinated with chlorine gas to generate dichloroisocyanuric acid, and the dichloroisocyanuric acid filter cake obtained by slurry filtration can be fully washed with water to remove sodium chloride in the filter cake to obtain dichloroisocyanuric acid. The wet dichloroisocyanuric acid is added with water to the slurry, or put into the mother liquor of sodium dichloroisocyanurate, and caustic soda is added dropwise according to the molar ratio of 1:1 for neutralization reaction. The reaction solution is cooled, crystallized, and filtered to obtain wet sodium dichloroisocyanurate, and then dried to obtain powdered sodium dichloroisocyanurate or its hydrate. (2) The sodium hypochlorite method first reacts by caustic soda and chlorine to generate a suitable concentration of sodium hypochlorite solution. According to the concentration of sodium hypochlorite solution, it can be divided into two processes: high and low concentration. Sodium hypochlorite reacts with cyanuric acid to produce dichloroisocyanuric acid and sodium hydroxide. In order to control the pH value of the reaction, the method of supplementing chlorine can be used to make the sodium hydroxide and chlorine generated by the reaction continue to participate in the reaction. So that the reaction raw materials are fully utilized. However, because chlorine gas participates in the chlorination reaction, the control requirements for the raw material cyanuric acid and the operating conditions of the reaction are relatively strict, otherwise nitrogen trichloride explosion accidents are prone to occur; in addition, the method of neutralization of inorganic acids (such as hydrochloric acid) can also be used This method does not have chlorine directly involved in the reaction, so the operation is easy to control, but the use of raw material sodium hypochlorite is incomplete. |
| use | used as industrial water fungicide, drinking water disinfectant, swimming pool disinfectant, fabric finishing agent, etc. used as disinfectant, can be used for swimming pool, drinking water disinfection, preventive disinfection and environmental disinfection in various places. It can be used for raising silkworms, livestock, poultry and fish for disinfection. It can also be used for wool shrink-proof finishing, textile industry bleaching, industrial circulating water algae removal, and rubber chlorinating agent. This product is efficient, stable in performance, and has no adverse effects on human body. GB 2760-96 stipulates that it is a processing aid for food industry. It can be used for disinfection of dairy products and water. Can quickly kill all kinds of bacteria, fungi, spores and hepatitis A, hepatitis B virus. It can be widely used in swimming pools, family bathrooms, living utensils, fruits and vegetables and indoor disinfection. Used for wool anti-felting finishing, it has the advantages of safe and convenient use and stable storage. It is also used as an efficient and fast cleaning, sterilization and detoxifying agent, bleaching agent, decolorant, and preservative. Basolan DC is potassium dichloroisocyanurate, which can be used for anti-felting finishing of wool in the acidic or weakly alkaline range (pH4-8). It has a good anti-felting effect in the acidic range; in the alkaline range, the wool has a good hand feeling and increases its luster. But it also makes the fabric yellow. |
| production method | is obtained by chlorination of cyanuric acid. It is made by heating ammonium chloride and urea together, acidification, alkali dissolution, chlorination, and then drying. |
