Chemical Properties

Crystals Having a pungent odor. Soluble in chloroform, carbon tetrachloride, ethanol, hot ether, acetone, dioxane, slightly soluble in water.


cyanuric chloride is an important fine chemical product, with a wide range of uses, it is the intermediate in pesticide industry, and the manufacture of reactive dyes raw material, it can used as all kinds of organic industrial production additives, such as fluorescent brighteners , textiles shrink-proof agents, surface active agents, it is one of the materials used in the manufacture of defense explosives and rubber accelerator and it is also the material for the synthesis of drugs by the pesticide and pharmaceutical industry.

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.

Cyanurchloride is an intermediate to manufacture of agrochemicals (triazine herbicides), dyestuffs, optical brighteners, tanning agents, reactive dyes, UV-absorbing agent, softening agents and pharmaceuticals, as well as block-builders for plastics. Product Data Sheet


Cyanurchloride is an intermediate to manufacture of agrochemicals, dyestuffs, optical brighteners, tanning agents, softening agents and pharmaceuticals, as well as block-builders for plastics.


Reagent for the conversion of alcohols to chlorides and for the immobilization of microorganisms and enzymes.1


Cyanuric Chloride is extensively used in the preparation of the triazine-class pesticides and herbicides. Cyanuric chloride is also used as a precursor to dyes and crosslinking agents due to the react ive chlorine atoms towards nucleophilic substitution reactions. Cyanuric chloride derivatives possess a large spectrum of activities as antibacterial and anticancer agents.


Intermediate in the synthesis of active dyes, agricultural products, and drug substances. Reagent in organic synthesis. Coupling agent for nucleic acids and proteins; cyanuric chloride-activated paper is used in capillary and electroblotting applications, dot tests, and hybridization protocols.


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.

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.

Air & Water Reactions

Reacts exothermically with water, especially if catalyzed or heated, to generate fumes of hydrochloric acid. Very slightly soluble in water.

Reactivity Profile

Cyanuric chloride 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).

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.

Safety Profile

Poison by ingestion, inhalation, and intravenous routes. Questionable carcinogen with experimental tumorigenic data. Experimental reproductive effects. A corrosive. A skin and severe eye irritant. An allergen. Has been reported as causing irritation of mucous membranes and heart rhythm disturbances in humans. Violent reaction with water - (above 30°C), acetone + water, methanol, methanol + sodium hydrogen carbonate, 2- ethoxyethanol, dimethyl formamide, 3- butanone + sodium hydroxide + water, allyl alcohol + sodium hydroxide + water (at 28℃). When heated to decomposition it emits toxic fumes of Cland NOx. See also CHLORIDES.

Purification Methods

TCT crystallises from CCl4 or pet ether (b 90-100o) and is dried under vacuum. It has also been recrystallised twice from anhydrous *benzene immediately before use [Abuchowski et al. J Biol Chem 252 3582 1977]. [Beilstein 26 III/IV 66.]
