Abstract:

Bis-substituted-phenylaldehyde-bis-(p-aminophenyl)methane-schiff base (SB) of general formula (R)-phCH=N-ph-CH2-ph-N=CHph(R),where R is p-NO2, m-NO2,p-OH, o-OH, p-Cl,-H, p-OCH3, were synthesized and characterized. They are thermolabile and undergo thermochrocism and thermal decomposition after melting. The TG. and DSC measurement were recorded in dynamic air and interpreted.

Key words: Bis-substituted-phenylaldehyde-bis-(p-aminophenyl)methane-schiff, base Synthesis, thermo-hrocis
