  • CAS Number: 87 - 90 - 1
  • English Name: Trichloroisocyanuric acid
  • English Aliases: TCCA, ACL 85, 90 plus, Isocyanuric chloride, trichlorocyanuric acid, 1,3,5 - Trichloro - 1,3,5 - triazine - 2,4,6 - trione, etc.
• Physical and Chemical Properties
  • Appearance: White or off - white powder or granular powder, with a pungent odor of hypochlorous acid.
  • Density: 2.19g/cm³
  • Melting Point: 245 - 251℃
  • Boiling Point: 272.3℃ at 760 mmHg
  • Solubility: Slightly soluble in water, with a solubility of 1.2g/100g at 25℃, and easily soluble in organic solvents. For example, the solubility in acetone is 36g/100g at 30℃.
  • pH Value: The pH value of a 1% aqueous solution is 2.7 - 3.3.
  • Active Chlorine Content: Not less than 90% for first - class products.
  • Moisture Content: Not more than 0.5%.
• Uses
  • Disinfection and Sterilization: Widely used in food processing, drinking water disinfection, sericulture, and rice seed disinfection. It can kill almost all fungi, bacteria, and virus spores, and is especially effective against hepatitis A and B viruses, as well as has a good disinfection effect on sexually transmitted viruses and HIV. It can also be used for the disinfection and deodorization of hospital sewage, laundry items, and public waste.
  • Textile Industry: Used as a bleaching agent, suitable for the bleaching treatment of cotton, linen, wool, synthetic fibers, and blended fibers. Its performance is better than that of sodium hypochlorite and bleaching powder.
  • Food Industry: Replaces chloramine T for food disinfection. Its active chlorine content is three times that of chloramine T, and it can also be used as a decolorizing and deodorizing agent for dextrin.
  • Wool Textile Industry: Used as a wool shrink - resistant agent, which can replace potassium bromate.
  • Rubber Industry: Used as a chlorinating agent in the rubber industry.
  • Industrial Oxidant: Can replace hypochlorite as a high - quality oxidant.
  • Organic Synthesis: It is a raw material in the organic synthesis industry, and can be used to synthesize a variety of organic substances, such as isocyanuric acid tris (2 - hydroxyethyl) ester.
• Synthesis Methods
  • Chlorine Gas Method: The process is simple, but during the reaction, it is easy to generate explosive nitrogen trichloride (NCl₃), with potential safety hazards.
  • Liquid Chlorinating Agent Method: The reaction is rapid and does not pollute the environment, but hypochlorous acid is unstable, which will lead to a decrease in product yield.
  • Solvent Method: It has the advantages of continuous operation, automation, large - scale production, and low pollution, and is adopted by developed countries for large - scale production.
  • Deep Chlorination of Sodium Dichloroisocyanurate Method: Cyanuric acid reacts with sodium hypochlorite solution to produce sodium dichloroisocyanurate, which is then deeply chlorinated to produce trichloroisocyanuric acid.
• Packaging and Storage
  • Packaging: Commonly packed in 25 - kg plastic - lined woven bags. There are also other packaging forms, such as 0.5 - kg to 1 - kg anti - counterfeiting boxes, 1 - kg double - lid barrels, 5 - kg or 10 - kg European - style barrels, and 50 - kg square plastic barrels.
  • Storage: Should be stored separately from strong reducing agents, ammonia, ammonium salts, amines, nitrogen - containing compounds, acids, strong alkalis, humid air, or water. Store in a cool, dry, and well - ventilated warehouse, away from fire sources and heat sources.
