Schiff base ,indicates many special performances in analytical chemistry, polymer chemistry, catalysis, pharmaceutical and so on, is a very important kind of nitrogen-containing organic compounds and becomes one of the study focus.
In the synthesis of Schiff a variety of amine and carbonyl groups with different aldehydes and ketones are chosed flexibility , changed the substituent, to synthesize different schiff base. In this thesis, used the direct synthesis , the 4 - hydroxybenzaldehyde and aniline, p-toluidine, o-toluidine, anisidine, p-chloroaniline was synthesized different Schiff base,by measuring the ultraviolet, infrared and nuclear magnetic resonance to characterize the product of the spectrum. |
