| Hazard Information | Back Directory | [General Description]
Crystals. | [Reactivity Profile]
An amide and amine. Organic amides/imides react with azo and diazo compounds to generate toxic gases. Flammable gases are formed by the reaction of organic amides/imides with strong reducing agents. Amides are very weak bases (weaker than water). Imides are less basic yet and in fact react with strong bases to form salts. That is, they can react as acids. Mixing amides with dehydrating agents such as P2O5 or SOCl2 generates the corresponding nitrile. The combustion of these compounds generate mixed oxides of nitrogen (NOx) | [Air & Water Reactions]

white powder | [Definition]
ChEBI: The keto tautomer of cyanuric acid. | [Definition]
cyanuric acid: A white crystallinewater-soluble trimer of cyanic acid,(HNCO)3. It is a cyclic compound havinga six-membered ring made of alternatingimide (NH) and carbonyl(CO) groups (i.e. three -NH-C(O)-units). It can also exist in a phenolicform (three -N=C(OH)- units). | [Production Methods]
Cyanuric acid is an odorless, crystalline powder. Chlorinated
isocyanuratesareusuallypreparedbycontrolledchlorinationof
the sodium or potassium salts of cyanuric acid. Other monomeric
isocyanurates made from the parent compound include
tris(2-hydroxyethyl)isocyanurate and triallyl cyanurate. | [Flammability and Explosibility]

3.Mainly used in the production of new bleaching agent, disinfectant, water treatment agent and resin, paint and metal cyanide corrosion inhibitor, etc.
4.Used for the synthesis of chloro derivatives, trichloroisocyanuric acid, dichloro isocyano uric acid sodium or potassium; used for synthesizing cyanuric acid-formaldehyde resin, epoxy resin, antioxidant, coatings, adhesives, pesticides, herbicides, metal cyanide inhibitor and polymer modifier; used in the manufacture of halotrizinol.
| [Methods of production]
It is obtained by the polymerization of urea. Mixed urea and ammonium chloride, heating and melting, stirring and temperature to 210℃, solution thickened, warming up to 230℃, melting gradually solidified, stir fry evenly, continue to heat up to 250℃, thermal insulation for 15 min, cold to 100℃, adding a small amount of water immersion and down to room temperature in water soaking crushed, filtered solids. The water and hydrochloric acid are added into the solid, stirring and heating to 110 ℃, insulation for 3 h, supplementing with hydrochloric acid and water, cooling to 30 ℃, and washing to neutral, filter, filter cake with water washing and drying to obtain the product. The product purity is ≥95%, consumption of urea 1200kg per ton of product.
