Cyanuric Acid and Cyanurates
... Cyanuric chloride dissolves poorly in water. However, when its aqueous solution is allowed to stand or is heated, it undergoes hydrolysis to form cyanuric acid: C 3 N 3 Cl 3 + 3H 2 O = C 3 N 3 ( OH ) 3 + 3HCl. Thus, cyanuric chloride can be regarded as the oxychloride of this acid. On the contrary, ...
