Synthesis of new ionic liquids based on dicationic imidazolium and their anti-corrosion performances

Ionic liquids with high environmental value and adsorption properties are a requirement for the new trend for corrosion inhibitors. Here, we synthesis three new ionic liquids based on dicationic imidazolium (IL1, IL2 and IL3) to produce green inhibitors for stainless steel corrosion in acidic environment. The anionic portion of all prepared ionic liquids is BF4−. New ionic liquids were recognized by means of element inspection, FT-IR, TGA and 1H...
