【Abstract】 Accumulating on copper surface very guickly in agueous solution, 2 alkylbenzimidazole is an ideal inhibitor and anti corrosion chemical for copper. In this paper, the thermal stability of 2 alkylbenzoimidazoles on copper, which have been treated at 150, 200 and 250 ℃ respectively, has been studied by FTIR. It is indicated that 2 alkylbenzoimidazole on copper has a poor thermal stability as the chain length of alkyl substituent increased, compared with that of 2 alkylimidazoles on copper, the thermal stability of 2 alkylbenzoimidazoles was improved due to their special molecular structure.
