C4mim

C4mim is a shorthand for 1-n-butyl-3-methylimidazolium salts. These are ionic liquids based on imidazole chemistry. A common example of such is [C4mim] [Cl] , or 1-n-butyl-3-methylimidazolium chloride. These salts are currently of interest in industry due their ability to be infinitely recycled and their amenability to solvation at room temperature, making them excellent green solvents.
