Determination of some imines structures derived from salicylaldehyde with phenylene diamines by physical methods

The project is concerned with the preparation of four imines derived from salicylaldehyde with some aromatic primary amines, namely, o,m and p–phenylene diamine.These imines were identified by physical means available, namely the melting points, UV and IR spectra . The study led to the investigation of intra and inter molecular hydrogen bondings in these imines . Finally, the influence of intermolecular hydrogen bonding on association (polymerziation) in imines was included and its effect on the melting points of imines was also discussed .
