A series of seven azomethines has been synthesized from p-nitrobenzaldehyde and different substituted anilines. The structures of products have been determined by the data of IR-spectra. All obtained azomethines have metallic inhibition corrosion capacities on CT-3 steel and aluminum in different levels: the protection effects were 41-57% on CT-3 steel and 83-92% on aluminum. The influences of structures to their metallic inhibition corrosion capacities have been discussed.
