Cyanuric chloride: Introduction Cyanuric chloride has been known7 since 1827 when it was considered to be the trichloride of cyanogen. Liebig was determined its composition. Liebig prepared it by passing chlorine over dry potassium thiocyanate. Converted impure cyanogen chloride to cyanuric chloride by Serullas7. Reactions take place with sunlight. The cyanuric chloride was considered to be an isomer rather than the trimer of cyanogen chloride for some years. 1 As late as 1867, the trimer to monomer relationship of cyanuric chloride and cyanogen chloride was misunderstood151. The Infrared and Ultraviolet spectra (UV-IR)123 support the triazine structure. That result indicate that the chlorine atoms are on the Carbon atoms as shown in figure …show more content…

It melts44 at 145.750 C and boils at 1980 C. The cryoscopic constant for purity is 1.7 mole % impurity/degree of melting point lowering.137a the IR 44,155 of solid cyanuric chloride in Nujol and perfluorokerosene shows strong absorption bands at 1505, 1260 and 850 cm-1 regions. In valence-bond discussion of the unknown s-triazine the data used in ultraviolet absorption spectrum has been reported for ethyl alcohol solutions123 and for cyclohexane solutions156. Synthetic method: 1. From Cyanogen Chloride: The trimerization of cyanogen chloride gives cyanuric chloride. In and inert diluent in the presence of hydrogen chloride.160 in other reaction At 00 in chloroform-dioxane in the presence of hydrogen chloride159. Actually activated carbon alone is probably the most efficient catalyst. 164 It operates specifically in the case of cyanogen chloride. This is confirmed 164 by extensive research with other familiar high-surface agents. 2. From Hydrocyanic Acid159: Diels 153 develop a practical laboratory synthesis of cyanuric chloride from a method originated by Kalson166. It improved by Fries 167 and Lemoult 155. The trace of alcohol is necessary. After formation of chloral , it serves as an intermediate 43 and forms and addition compound with
