ABSTRACT
In the reaction between 5-formyl ethylvanillin and aromatic amines in equimolecularratio, Schiff bases are formed with raised yields. By the Schiff bases formation,, can beobserved, that from the two carbonyl groups of the 5-formyl ethylvanillin molecule, the formylgroup situated in the ortho position towards the hydroxyl group is more reactive. The synthesizedSchiff bases were characterized by means of IR, 1H-, and 13C-NMR spectra.
