Key Applications
1. Advanced Solvent & Extraction Agent
Due to its low vapor pressure and high solvency, it is an excellent medium for dissolving a variety of organic and inorganic compounds. It has been widely studied for:
-
Organic synthesis as a reaction medium.
-
Liquid–liquid extraction in separation processes.
-
Catalyst recycling for sustainable chemistry.
Example research: EMIM DCA’s ability to selectively extract aromatics from hydrocarbon mixtures has been documented in ScienceDirect studies.
2. Fuel Desulfurization (Extractive & Oxidative)
One of EMIM DCA’s most promising applications is in removing sulfur compounds from fuels. Both extractive desulfurization (EDS) and oxidative desulfurization (ODS) processes benefit from its high selectivity toward sulfur-containing molecules like thiophene and dibenzothiophene.
-
Reduced sulfur emissions meet stringent environmental regulations.
-
Potential for energy-efficient refinery upgrades.
3. Electrolyte for Energy Storage & Electrochemistry
The ionic conductivity and electrochemical stability window of EMIM DCA make it a valuable electrolyte in:
-
Supercapacitors
-
Lithium-ion and sodium-ion batteries
