Abstract :In this study, to determine the pKa values of 2-ethoxy-6-insert ignore into journalissuearticles values(3-substitue-4,5-dihydro-1H-1,2,4-triazol-5-one-4-yl-azomethine);-phenyl benzoates 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, acetone and N,N-dimethylformamide insert ignore into journalissuearticles values(DMF);, and graphs were drawn for all cases. In addition, the effects of solvents and molecular structure upon acidity compounds 1-9 were also determined and discussed. The half-neutralization potential values and the corresponding pKa values were determined by half neutralization method.
