Cyanuric Chloride

(2,4,6-trichloro-l,3,5-triazine), the acid chloride of cyanuric acid; a white crystalline compound, with a pungent odor, a melting point of 146°C, a boiling point of 190°C, and a density of 1.32 g/cm³ (at 20°C).

Cyanuric chloride is readily soluble in acetone, chloroform, and other organic solvents but is very slightly soluble in water, in which it gradually hydrolyzes, forming cyanuric acid. The chlorine atoms in cyanuric chloride may be replaced by various functional groups, for example, RO— (by the action of alcohols and phenols), RNH— (by the action of primary amines), or NH₂— (by the action of ammonia).

The major industrial method for the preparation of cyanuric chloride is the catalytic trimerization of cyanogen chloride (3ClCN→C₃N₃Cl₃), which is carried out either in the gas phase, at temperatures of 350°–450°C in the presence of activated charcoal, or in the liquid phase, at a temperature of 300°C and a pressure of 4 meganewtons/m² (40 kilograms-force/cm²) in the presence of hydrochloric acid or ferric chloride.

Cyanuric chloride is used mainly in the production of herbicides; it is also used in the production of optical brighteners and active azo dyes.

Nanocrystalline "graphitic" carbon nitride was prepared through the solvothermal reaction (1) between cyanuric chloride ([C.sub.3][N.sub.3][Cl.sub.3]) and sodium amide (NaN[H.sub.2]) by following the procedure reported by Guo et al.

Reexamination of Solvothermal Synthesis of Layered Carbon Nitride

Cyanuric chloride (3.69 g, 0.02 mole) in acetone (50 mL) was stirred along with addition of neutral solution of 4 (9.68 g, 0.02 mol) in small portions at a temperature below 5AdegC for a period of 1h.

The four misclassified chemicals were diethyl maleate, butyl glycidyl ether, lyral and cyanuric chloride. The only false-negative prediction was cyanuric chloride, which is classified as 1A in CLP and as no cat in our model, whereas the remaining three chemicals are classified as CLP 1B but were predicted as 1A.
