-
A new series of Gemini imidazoline quaternary ammonium salts as corrosion inhibitor(S-HSJ) was synthesized.The corrosion inhibition performance,the influences of carbon chain length in lipophilic structure,corrosion time and corrosion inhibitor concentration were investigated comprehensively.The experiments for copper,brass,aluminum and tinplate were conducted in 5% hydrochloric acid solutions with the help of mass loss method.The results show that the inhibition effects of the series of S-HSJ corrosion inhibitor are better than those of traditional quaternary ammonium salts and benzotriazole for several metals.The inhibition efficiency of S-HSJ-16 can reach 94%~99% when an amount of 0.1% such an inhibitor was added.The complex inhibition ability with anion surfactant shows an obviously synergistic effect.
