Synthesis and thermophysical properties of imidazolium-based bronsted acidic ionic liquids

A range of imidazolium-based Bronsted acidic ionic liquids (ILs) have been synthesized by varying the side chain length of the alkyl and alkyl sulfonic group incorporated to the C1 and C3 positions in the imidazolium ring respectively with a fixed HSO4- anion. The synthesized ILs were characterized...
