Abstract

Six examples of 1-isopropyl imidazolium cation based brønsted acid ionic liquids with counter anions such as OTf--, CH3SO3 -, C6H5SO3 -, BF4 -, PF6 -,NO3 - have been synthesized by acid- base neutralization reaction and anion exchange metathesis reaction methods. The structure of the reported ionic liquids has been confirmed by H1 NMR and mass spectrometry.
