1,3-Diethylimidazolium diethyl phosphate, CAS: 945406-32-6

Key Applications:

Green Solvent for Biocatalysis and Biomass Processing

• Serves as a low‑volatility, thermally stable medium for enzyme‑catalyzed reactions, improving selectivity and conversion in esterification, transesterification, and oxidation systems.
• Efficiently dissolves lignocellulosic biomass, enabling pretreatment, fractionation, and valorization of cellulose, hemicellulose, and lignin.
• Supports ionic‑liquid–tolerant enzyme systems, enabling integrated biorefinery workflows.

Electrolyte and Additive in Energy Storage

• Functions as a non‑flammable electrolyte component in lithium‑ion, sodium‑ion, and emerging multivalent battery chemistries.
• Enhances ionic conductivity and electrode interfacial stability when blended with carbonate or phosphate‑based co‑solvents.
• Useful as a proton‑conducting medium in polymer electrolyte membranes and solid‑state devices.

Surfactant, Emulsifier & Phase‑Behavior Modifier

• Exhibits amphiphilic behavior that supports microemulsion formation, phase transfer, and colloidal stabilization.
• Applied in nanoparticle synthesis, where it controls nucleation, growth, and dispersion stability.
• Useful in CO₂‑responsive systems, enabling reversible emulsification and separation.

Catalysis & Reaction Engineering

• Acts as a Brønsted acidic ionic liquid, enabling acid‑catalyzed transformations such as alkylation, esterification, dehydration, and biomass‑derived platform molecule upgrading.
• Provides tunable polarity and acidity for selective catalytic pathways in both homogeneous and supported IL phases (SILP).

Polymer & Materials Processing

• Serves as a plasticizer or processing aid for cellulose, chitosan, and other biopolymers, improving solubility and mechanical properties.
• Enables ion‑conducting polymer blends for membranes, coatings, and antistatic materials.
• Useful in sol–gel processing and inorganic–organic hybrid material synthesis.

Separation Science & Extraction

• Effective in liquid–liquid extraction of metal ions, organic acids, and bioactive compounds due to its tunable hydrophilicity.
• Supports supported ionic liquid membranes (SILMs) for selective gas and vapor separations.
• Applied in reactive extraction systems where acidity and polarity drive selective partitioning.
