K SIVARAMA PRASAD, P VASANTA KUMAR, M C CHOWDARY

Abstract


The formation constants of the Schiff base between salicylaldehyde and aniline in water-methanol and water-dioxan mixtures of varying composition have been determined spectrophotometricatly. The formation constants were found to vary with the mole fraction of water in both the solvent media.

Keywords


Schiff base; formation constant; spectrophotometer; modified Job's method; aniline; salicylaldehyde; salicylidene aniline.
