Abstract
Three gemini ionic liquids namely, 3,3â²-(1,4-phenylenebis(methylene))bis(1-alkyl-1H-imidazol-3-ium)bromide IL1, IL2, and IL3, were prepared and characterized via the conventional tools of analysis, elemental analysis, IR, and 1H NMR spectroscopy. The thermal stability of these compounds was studied, using thermogravimetric analysis (TGA) technique. The gemini ionic liquids were tested as corrosion inhibitors for stainless steel (304 SS) in 0.5â¯M H2SO4 solution using electrochemical techniques. The Results showed that gemini ionic liquids were effective with optimal corrosion inhibition values of 90.7%, 97.3% and 82.6% for IL1, IL2 and IL3, respectively. The data confirmed also gemini ionic liquids are mixed type inhibitors.
