Abstract
Reactivity of alkaline salts of isocyanuric acid has been studied. It has been established that the nucleophilic substitution is not selective because of the protonic exchanges between salts and substituted derivatives. The synthesis of mono or trisubstituted derivative is due to secondary reactions and to solvent effects. With this study, it has been possible to settle a method to prepare mono and trisubstituted derivatives of isocyanuric acid.
