| Hazard Information | Back Directory | [General Description]
A colorless crystalline solid with a pungent odor. Melting point 146°C. Density 1.32 g/cm3. Very slightly soluble in water. Toxic by ingestion and inhalation of vapors. Irritates skin and eyes. Used to make dyes. | [Reactivity Profile]
CYANURIC CHLORIDE(108-77-0) reacts rapidly and exothermically with water to generate hydrogen chloride. A mixture with water in an industrial reactor with refrigeration turned off developed pressure that blew gaskets and filled the building with flammable vapors. An explosion occurred when the vapors were ignited [MCA Case History 1869(1972)]. Runaway reactions have occurred with acetone/water; methanol/water, ethoxyethanol/water, allyl alcohol/sodium hydroxide/water, 2-butanone/sodium hydroxide/water, and methanol/sodium bicarbonate [Loss Prev. Bull., 1979, (25), 21]. Reacts with methanol to give gaseous methyl chloride. Reacts rapidly with bicarbonates to generate gaseous carbon dioxide. Reacts vigorously with dimethyl formamide (DMF) to form carbon dioxide after a deceptive induction period [BCISC Quart. Safety Summ., 1960, 35, 24]. Can react with reducing agents to generate heat and products that may be gaseous (causing pressurization of closed containers). The products may themselves be capable of further reactions (such as combustion in the air). | [Air & Water Reactions]
Reacts exothermically with water, especially if catalyzed or heated, to generate fumes of hydrochloric acid. Very slightly soluble in water. | [Health Hazard]
TOXIC; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death. Reaction with water or moist air will release toxic, corrosive or flammable gases. Reaction with water may generate much heat that will increase the concentration of fumes in the air. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution. | [Fire Hazard]
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Vapors may accumulate in confined areas (basement, tanks, hopper/tank cars etc.). Substance will react with water (some violently), releasing corrosive and/or toxic gases and runoff. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated or if contaminated with water. | [Definition]
ChEBI: A chloro-1,3,5-triazine in which the triazine ring is substituted on each carbon by chlorine. Its main use is in the preparation of the triazine-class pesticides. | [Production Methods]
Cyanuric chloride is obtained by the trimerization of cyanogen
chloride in organic solvents, in the presence of acidic
catalysts, and carried out in a gaseous phase at 200–500C.
Cyanuric chloride is used as a chemical intermediate. It is the
precursor to the herbicide atrazine. | [Flammability and Explosibility]

Cyanuric chloride, white crystals with a strong irritant chlorine odor , is corrosive to the skin, having eye irritation and tearing property. Melting point 145 ℃, boiling point 190 ℃, UVλmax241nm (ethanol).it is Soluble in ethanol, ethyl ether, chloroform, acetic acid and acrylonitrile, insoluble in cold water. cooling of reaction of Cyanuric chloride and water is slow, when it is heated it is rapidly hydrolyzed to cyanuric acid (C3H3O3N3) and hydrochloric acid, the product are relatively soluble in water, so you can use the extraction method of separating. It Reacts With concentrated nitric acid and concentrated sulfuric acid at room temperature to be partial conversion of cyanuric acid, and it reacts with the sodium alkoxide to generate cyanuric acid triester, and it can also react with ammonia, amines, phenols and so on.
In recent years, there is rapid growth in consumption of cyanuric chloride in China, from 1998 to 2004 the average annual growth rate of Apparent consumption was about 32.2% ,in 2005, cyanuric chloride demand reached 50,000 tons, according to forecasts, from 2007 to 2012 cyanuric chloride will continue rapid growth in average rate of 6.0% , the market is very promising. Since cyanuric chloride subsequent products are enormous , the market demand is large, national research institutions and related businesses have continued to develop its downstream products, and open cyanuric chloride applications. Therefore, the new product by the cyanuric chloride derivatives are emerging, the market demand will be further expanded.

| [production method]
Cyanuric chloride production process usually consists of two steps : chloride cyanogen polymerization and chloride cyanogen preparation . There are many ways to generate chloride cyanogen, such as the synthesis of methyl thiocyanate and chlorine, hydrocyanic acid is dissolved in chloroform and chlorine gas is put in to synthesize , hydrocyanic acid method, sodium cyanide, urea, hydrocyanic acid direct method of chlorine and cyanuric chloride and the like, the current production of industrial cyanuric chloride generally uses sodium cyanide and hydrocyanic acid as raw materials in two ways. 1. Sodium cyanide method : using sodium cyanide as raw materials after the reaction of chlorine and cyanuric chloride, it is polymerized to form cyanuric chloride, it is quenched,then after crystallization ,the product is obtained. Material consumption fixed: sodium cyanide 1073kg/t, chlorine 1700kg/t. 2. The method of hydrocyanic acid :with hydrocyanic acid as raw materials ,chloride cyanogen is produced by the reaction of chlorine, and then use polymerization to generate cyanuric chloride, quench, crystallize , the product is obtained. Material consumption fixed: hydrocyanic acid 500kg/t, chlorine 1200kg/t.
