Cyanuric Acid is a white crystal that precipitates from water with two units of crystalline water.

It is slightly bitter, basically non-toxic, soluble in hot water, slightly soluble in cold water, acidic in aqueous solution, soluble in an aqueous solution of potassium hydroxide and sodium hydroxide, insoluble in cold alcohol, ether, benzene and other organic solvents.

It can product by putting the cyanuric acid powder into the tumbling tray, gradually add urea, heating until no ammonia gas is generated. A small portion is taken out, crushed, dissolved in sulfuric acid, boiled, centrifuged, filtered, washed, and dried to get the finished Cyanuric Acid.


Cyanuric acid synthesizes chlorinated derivatives, salts, and lipids, including trichloroisocyanuric acid, dichloroisocyanuric acid, sodium or potassium. It is also used in the synthesis of cyanuric acid-formaldehyde resins, epoxy resins.

It is also a component of antioxidants, paints, lacquers, adhesives, pesticide herbicides, metal cyanide corrosion inhibitors, polymer modifiers; in the pharmaceutical field, and it is also used to produce the drug halotriazine.

In addition, it can be synthesized into a new bleaching agent, also can be used for swimming pool chlorine stabilizer, sterilization, decontamination, also can be directly used in nylon, cyc, combustion agent and cosmetic additives, laminated plastics and high-temperature glass fiber reinforced plastic and other production materials.
