This ionic liquid solidifies below its melting point of 15°C, requiring storage above this temperature to remain liquid. No additional handling constraints are detailed in the available specifications.
- Temperature Constraint: This material must be stored at temperatures above 15°C to avoid phase transition to solid.
How does the 15°C melting point of [C2MIm]BF4 constrain its use in low-temperature electrochemical studies?
The melting point of 15°C means [C2MIm]BF4 transitions from a liquid to a solid below this temperature, limiting its applicability as a fluid electrolyte or solvent in experiments conducted below 15°C. Research protocols requiring sub-ambient conditions must incorporate heating stages or alternative ionic liquids with lower melting points. This phase transition profile is explicitly specified in the product's technical parameters.
What compatibility issues arise from the water solubility of [C2MIm]BF4 in electrochemical applications?
The complete water solubility of [C2MIm]BF4 means it readily absorbs atmospheric moisture, which can introduce water contamination that degrades electrochemical performance and electrolyte purity. For research requiring anhydrous conditions, rigorous drying procedures and inert atmosphere handling are mandatory to maintain the material's integrity. The product is explicitly listed with 'Water: Soluble' as a solubility characteristic, confirming its hydrophilic nature.
What handling and storage requirements should be observed for [C2MIm]BF4 based on its flash point and melting point?
Storage must be temperature-controlled above 15°C to prevent solidification, and containers must be sealed tightly to prevent moisture uptake due to water solubility. Although the flash point is high at 350°C, standard laboratory safety practices including fume hood use and PPE are required. The product is sold exclusively for laboratory research, and users must comply with all applicable safety regulations.
1-Ethyl-3-methylimidazolium tetrafluoroborate (EMIM BF4) is a research-grade ionic liquid with a high flash point of 350°C and a melting point of 15°C, offering thermal resilience and water solubility for electrochemical and synthesis applications, but requiring careful temperature management and moisture control.
Positive
- High thermal resilience: With a verified flash point of 350°C, this material enables safe operation at elevated temperatures, supporting exothermic reactions and high-temperature electrochemical setups.
- Hydrophilic solubility: Full water solubility facilitates straightforward solution-phase preparation and simplifies integration into aqueous reaction systems, reducing solvent compatibility concerns.
Trade-offs
- Low melting point near ambient: With a melting point of 15°C, the material may solidify under typical laboratory cold conditions, necessitating temperature control or preheating to maintain a liquid state.
- Hygroscopic due to water solubility: The material's hydrophilic nature increases risk of moisture absorption from ambient air, potentially altering purity and affecting performance in anhydrous electrochemical or synthetic applications.
