Abstract :A series of 3-alkylinsert ignore into journalissuearticles values(aryl);-4-[3-insert ignore into journalissuearticles values(2-metylbenzoxy);-4-methoxybenzylideneamino]-4,5-dihydro-1H-1,2,4-triazol-5-ones insert ignore into journalissuearticles values(1-9); were titrated potentiometrically with tetrabutylammonium hydroxide in four non-aqueous solvents such as isopropyl alcohol, tert-butyl alcohol, acetonitrile and N,N-dimethylformamide insert ignore into journalissuearticles values(DMF);, and graphs were drawn for all cases. The half-neutralization potential values and the corresponding pKa values were determined by half neutralization method. Thus, the effects of solvents and molecular structure upon acidity were discussed.
