white crystalline powder. The melting point was 225-235 °c. The volume relative density of powder is 0. 60~0. 65, and the volume relative density of powder is 0.90~0. 96. Solubility in water 0.8%, stable when dry. It is easy to decompose in case of acid and alkali. With strong oxidation. In the case of combustible materials, organic matter can be ignition and combustion. Reaction with nitrogen-containing compounds (such as ammonia, urea, etc.) to generate explosive nitrogen trichloride. Heat or easy to break down the moisture release of highly toxic smoke.
dichloroisocyanuric acid was obtained by chlorination of isocyanuric acid under certain conditions.
dichloroisocyanate is similar to chlorine and is an oxidizing bactericide. The product can gradually release organic compounds of hypochlorous acid or chlorine in the circulating cooling water, and it can be used in the circulating cooling water system instead of liquid chlorine or hypochlorite. The dosing method is generally impact-type dosing in the catchment. The concentration of sodium dichloroisocyanurate was 25-50mg/L. When the circulating water containing hydrocarbons (oil) is not more than 5 mg/L, there will be better treatment effect. However, when the circulating water system water cooled medium leakage occurs serious, hydrocarbons or amines on the circulation of excessive water pollution, it will affect the product treatment effect.
rat oral LD50: 745 mg/kg; Mouse oral LD50. 5 mg/kg. Dust can strongly irritate the eyes, skin and respiratory system. Has a stimulating effect on the gastrointestinal tract. Store in a cool, dry, well-ventilated non-combustible warehouse. Keep away from fire and heat source. The packaging is sealed. Moisture-proof, sunscreen. Should be stored separately from the reducing agent, combustible, combustible, etc.

application | sodium dichloroisocyanurate is a very efficient and strong oxidizing disinfectant, which can be used for external disinfection in clinic. it is a new type of systemic fungicide, which can kill various pathogenic microorganisms. |
use | when the pH value is less than or equal to 8.5, it has strong sterilization and algae killing ability and peeling of slime. Suitable for disinfection of drinking water and swimming pool water. It can also be used as fabric bleaching agent, wool spinning shrinking agent, etc. |
production method | sodium hydroxide and cyanuric acid are successively put into a chlorination kettle according to a molar ratio of 2: 1, and chlorinated by Cl2 at a pH value of 6.5-8.5 and 5-10 ℃ to obtain dichlorocyanuric acid. |
