Hypothesis
The sensitivity of the interactions between dimeric imidazolium salts and various solvents has not been reported so far.
Conclusion
The interactions between the solvent and imidazolium salt of butyl substituted ionic liquids are observed to give higher chemical shifts than in methyl substituted ones.
Supporting Evidence
- The study synthesized various dimeric ionic liquids and characterized them using NMR spectroscopy.
- Chemical shifts of the imidazolium protons were significantly affected by the choice of solvent and anion.
- The ionic liquids showed excellent yields in their synthesis, ranging from 82% to 95%.
Takeaway
The study looks at new types of ionic liquids and how they behave in different solvents, finding that some combinations change their properties more than others.
Methodology
The synthesis involved reacting α,α′-dibromo-p-xylene with imidazole derivatives in dry CH3CN, followed by metathesis reactions and Soxhlet extraction.
Limitations
The study does not explore the long-term stability of the synthesized ionic liquids or their performance in practical applications.
