One-pot synthesis of symmetric imidazolium ionic liquids N,N-disubstituted with long alkyl chains

摘要: The Debus–Radziszewski imidazole synthesis was adapted to directly yield long-chain imidazolium ionic liquids. Imidazolium acetate liquids with side-chains up sixteen carbon atoms were synthesised in excellent yields via an on-water, one-pot reaction. ILs acted as surfactants when dissolved various solvents. also derivatised acid metathesis the chloride, nitrate, and hydrogen oxalate derivatives. thermal behaviour of all determined thermogravimetric calorimetric analysis.
