• Basic Information
  • English Name: Cyanuric acid
  • Synonyms: 1,3,5 - Triazine - 2,4,6 - triol, Isocyanuric acid, 2,4,6 - Trihydroxy - 1,3,5 - triazine, etc.
  • CAS No.: 108 - 80 - 5
  • Molecular Formula: C₃H₃N₃O₃
  • Molecular Weight: 129.07
• Physical and Chemical Properties
  • Appearance: White crystalline powder or lumps, odorless, bitter - tasting, and hygroscopic.
  • Density: 1.768 g/cm³ (0℃).
  • Melting Point: 360℃ (decomposes).
  • Boiling Point: 150 - 180℃ (sublimes).
  • Solubility: 1 g can dissolve in about 200 ml of water (25℃). It is soluble in hot water, hot ethanol, pyridine, concentrated hydrochloric acid, and sulfuric acid, and also soluble in sodium hydroxide and potassium hydroxide aqueous solutions. It is insoluble in diethyl ether, acetone, benzene, and chloroform.
  • Stability: Stable, but decomposes to produce hydrocyanic acid above 330℃, and forms explosive products when in contact with chlorine gas.
• Preparation Methods
  • Urea Pyrolysis Method: Urea is pyrolyzed and cyclized to obtain cyanuric acid.
  • Urea - Salt Pyrolysis Method: Urea is mixed with sulfuric acid (or hydrochloric acid, nitric acid) in a certain proportion and reacted at 200℃ for about 5 hours. The yield is about 50% - 53%, and the content can reach 97% - 98%.
  • Nitric Oxide Method: Using hydrogen, carbon monoxide, and nitric oxide as raw materials, and palladium and iridium as catalysts, it is directly synthesized at 280 - 480℃. The yield is 60% - 75%, and this method has been industrialized.
• Uses
  • Synthesis of Chlorinated Derivatives: It is used to synthesize trichloroisocyanuric acid, sodium or potassium dichloroisocyanurate, etc. These chlorinated derivatives can be used as disinfectants for industrial water, swimming pool water, tableware disinfection, etc., and can also be used as sterilizers in agriculture and sericulture.
  • Stabilizer: It can be directly used as a stabilizer for swimming pool chlorine - treatment agents, and can also be used as a thermal stabilizer for butadiene rubber.
  • Flame - Retardant: It is used as a flame - retardant for nylon, polyester, and polyurethane foams.
  • Other Uses: It is a raw material for synthesizing cyanuric acid - formaldehyde resin, epoxy resin, etc., and can also be used to manufacture adhesives, coatings, oil - resistant insulating plasticizers, etc. It can also be used as an organic synthesis intermediate for the determination of manganese, etc.
• Packaging and Storage
  • Packaging: Usually packed in woven bags lined with plastic bags, and the common specification is 25 kg/bag.
  • Storage Conditions: It should be stored in a cool and ventilated warehouse, with the temperature below 30℃, and should be kept away from mixing with dangerous chemicals such as chlorine gas.
• Safety Information
  • Toxicity: It is basically non - toxic, but it is irritating to human skin and mucous membranes.
  • Risk Terms: R36/37/38, irritating to eyes, respiratory system and skin.
  • Safety Terms: S26, in case of contact with eyes, rinse immediately with plenty of water and seek medical advice; S37/39, wear suitable gloves and eye/face protection.
