Abstract The hydrolysis rate constants of 3-(N-methylcarbamoyl)-1, 3-diphenyltriazene (I), 3- (N-phenylcarbamoyl)-1, 3-diphenyltriazene (II) and 3-acetyl-1, 3-diphenyltriazene (III) have been determined in aqueous media within pH 0 to 14, H o to 3 and H-to 15. The hydrolysis at pH< 2 and pH> 11 show specific acid and base catalysis, respectively, whereas within pH 2 to 11 non-catalyzed hydrolysis takes place. Activation parameters of the non-catalyzed ...
