Abstract:
Novel methyl imidazolium based di-cationic, ionic liquids were synthesized using two
spacers, 1,3-dibromopropane and (E)-1,4-dibromo-2-butene. Seven different types of anions
were used to synthesize a total of 16 ionic liquids. Fourier transform infrared (FTIR) and 1H
nuclear magnetic resonance (NMR) spectroscopy were utilized to characterize ionic liquids.
The synthesized ionic liquids were tested for their antibacterial activity against a panel of
bacteria that included Escherichia coli, Staphylococcus aureus, Bacillus subtilis, Klebsiella
pneumonia and Methicillin-resistant Staphylococcus aureus. The results exhibited that the
ionic liquids had a good antibacterial activity against all the five tested bacteria.
