1-Ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (EMIM TFSI) is an ionic liquid with a melting point of -16.45°C and a decomposition temperature of 436°C, defining its operational liquid-phase range. The material is insoluble in water, ensuring clean phase separations in aqueous systems.
- Melting Point Constraint: Below -16.45°C, this ionic liquid solidifies and requires controlled temperature for liquid-phase operations.
- Decomposition Constraint: Above 436°C, the material undergoes thermal degradation and should not be exposed to such temperatures.
- Solubility Constraint: The material's water insolubility prevents dissolution in aqueous media but may require organic solvents for mixing.
How does the low melting point of [C2MIm] NTf2 affect its use in low-temperature electrochemical studies?
At -16.45°C, [C2MIm] NTf2 solidifies, which limits its fluidity and electrochemical performance below this temperature. However, above this threshold it remains a liquid, offering a wide operational range up to its decomposition temperature of 436°C.
Is [C2MIm] NTf2 compatible with aqueous reaction systems?
No, [C2MIm] NTf2 is fully insoluble in water, rendering it incompatible with aqueous environments. It is designed for non-aqueous applications where its hydrophobic profile facilitates clean phase separations.
What are the usage restrictions for [C2MIm] NTf2 in research laboratories?
[C2MIm] NTf2 is sold exclusively for laboratory research and is prohibited for commercial use, diagnostics, or human/animal applications. The buyer assumes all compliance liability as stated in the product disclaimer.
1-Ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (EMIM TFSI) is a research-grade ionic liquid with high thermal stability (decomposition at 436°C) and hydrophobic nature, suitable for non-aqueous electrochemical and catalytic studies. However, its water insolubility and research-only designation impose application constraints.
Positive
- High thermal stability: Maintains structural integrity up to a verified decomposition threshold of 436°C, enabling high-temperature electrochemical and catalytic investigations without premature degradation.
- Hydrophobic phase separation: Fully insoluble in aqueous environments, facilitating clean, efficient phase separations in biphasic reactions and water-sensitive systems.
Trade-offs
- Limited aqueous compatibility: Complete insolubility in water precludes direct use in aqueous electrolyte systems or biological buffers, restricting application to non-aqueous or hydrophobic media.
- Research-only usage restriction: Sold exclusively for laboratory research; prohibited for commercial, diagnostic, or human/animal applications, placing full compliance liability on the buyer.
