Required Equipment: Nitrile gloves, Safety goggles, Chemical fume hood
- Review safety documentation
Review the Safety Data Sheet (SDS) to confirm handling precautions specific to imidazolium-based ionic liquids. - Inspect container integrity
Inspect the sealed container for damage or leakage before opening in a fume hood. - Warm to working temperature
Warm the container to slightly above 22 °C if the material has solidified, until it becomes a free-flowing liquid. - Transfer under inert atmosphere
Transfer the required volume using dry, inert techniques to avoid moisture uptake and contamination.
What is the melting point of MMIM TFSI and how does it affect handling?
MMIM TFSI has a melting point of 22 °C, meaning it is a solid at typical room temperature (e.g., 20-25 °C) and may require gentle warming to become a liquid for easy handling. The product is supplied as a white solid, and the melting point is a key parameter for electrolyte preparation or solvent use in research.
What is the molecular weight and density of MMIM TFSI?
The molecular weight of MMIM TFSI is 377.28 g/mol, and its density is 1.57 g/cm³ at 25 °C. These physical constants are essential for calculating molar concentrations, preparing electrolyte solutions, and estimating volume-based quantities in electrochemical or separation experiments.
What are the storage and handling requirements for MMIM TFSI?
MMIM TFSI must be stored in a tightly closed container in a cool, dry, well-ventilated area, protected from moisture, water contamination, heat, and direct sunlight. Before handling, review the SDS and use appropriate protective equipment, as the material is sensitive to moisture and requires careful handling to maintain purity and performance.
This 99% pure 1,3-dimethylimidazolium bis(trifluoromethylsulfonyl)imide (MMIM TFSI) ionic liquid, with a melting point of 22 °C and density of 1.57 g/cm³ at 25 °C, is evaluated for research applications in electrochemistry and energy storage, where its defined ionic composition and solid-state handling at room temperature are key operational factors.
Positive
- Defined ionic composition: The 1,3-dimethylimidazolium cation paired with the bis(trifluoromethylsulfonyl)imide anion provides a clear, reproducible basis for electrolyte, solvent, and reaction-medium studies, enabling controlled comparison across experiments.
- Declared 99% purity: The listed 99% purity supports consistent material selection for research trials, reducing variability in electrochemical or catalytic screening where trace impurities can affect results.
Trade-offs
- Solid-state handling at room temperature: With a melting point of 22 °C, the material is a white solid under standard laboratory conditions, requiring melting or dissolution before use, which may add a preparation step for liquid-phase applications.
- Moisture and heat sensitivity: The product must be kept tightly closed in a cool, dry, well-ventilated area, protected from moisture, water contamination, heat, and direct sunlight, necessitating careful storage and handling protocols to maintain integrity.
