Abstract
The addition of phenol and effect of temperature and pH on the U.V. spectra of ortho, meta and para benzilnyledene aniline in ethanol as a solvent was studied. The thermodynamic parameters (G, H, S) were calculated in which the values of (G, H) are positive while the (S) is negative these support that the change in tautomerism shift to spontaneous and endothermic with systematic in (keto) form than (enol) form.
