TAILIEUCHUNG - About the metallic corrosion inhibition of some azomethines of cyclohexylamine series

The appropriate conditions have been found for syntheses of a series of azomethines using the reaction between cyclohexylamine and different aromatic aldehydes. The structures of products have been determined by the data of IR- and 1 H-NMR-spectra. All obtained azomethines have metallic inhibition corrosion capacities on CT-3 steel and aluminum in different levels. The influences of structures to their metallic inhibition corrosion capacities have been discussed. | Journal of Chemistry Vol. 43 3 P. 379 - 383 2005 ABOUT THE METALLIC CORROSION INHIBITION OF SOME AZOMETHINES OF CYCLOHEXYLAMINE SERIES Received 25th-March-2004 DANG NHU TAI NGUYEN MINH THAQ NGUYEN DINH THANH NGUYEN Duc MINH Faculty of Chemistry Hanoi University of Science SUMMARY The appropriate conditions have been found for syntheses of a series of azomethines using the reaction between cyclohexylamine and different aromatic aldehydes. The structures of products have been determined by the data of IR- and 1H-NMR-spectra. All obtained azomethines have metallic inhibition corrosion capacities on CT-3 steel and aluminum in different levels. The influences of structures to their metallic inhibition corrosion capacities have been discussed. I - INTRODUCTION In the present years the azomethines have been studied widely due to their metallic inhibition corrosion aside from useful properties 1 . However there are only two patents 3 4 about the synthesis and the study on inhibition corrosion on metals of azomethines containing hexamethylenediamine component with cinnamaldehyde and p-tolualdehyde. For searching the new compounds having high inhibition corrosion capacities on metals we have synthesized an azomethine series from cyclohexylamine and different substituted benzaldehydes and investigated their inhibition corrosion capacities on different metals CT-3 steel aluminum . . II - EXPERIMENTAL IR-spectra were recorded on NICOLET-760 Spectrometer in form of mixing with KBr and using reflex-measure method at the PetrolChemical Center Hanoi University of Science VNU . 1H-NMR spectra were recorded on BRUKER AVANCE Spectrometer German at 500 MHz solvent was DMSO-d6 with the internal reference TMS at the Lab of Structural Analysis-Institute of Chemistry-the National Center of Natural Science and Technology . The aluminum samples for this case are aluminum plates containing - Mn Fe - Cu Zn Ti Ni - 95 Al. The steel CT-3 samples containing .
