Industrial Applications of 1-ETHYL-3-METHYLIMIDAZOLIUM P-TOLUENESULFONATE
| Industry | Application | Process |
|---|---|---|
| Ion Liquid Synthesis | Used as a functionalized ionic liquid precursor for preparing imidazolium-based ionic liquids bearing specific functional groups | Undergoes substitution reactions with active-hydrogen compounds (e.g., amines, alcohols) to introduce sulfonyl-modified side chains |
| Organic Synthesis | Used as an alkylating or sulfonylating reagent in C–N and C–O bond formation | Undergoes SN2 nucleophilic substitution reactions with nucleophiles (e.g., sodium azide, thiols, phenolates) under anhydrous conditions |
| Electrochemistry | Used as an electrolyte additive to enhance electrode/electrolyte interfacial stability in lithium-ion batteries or supercapacitors | Added to carbonate-based base electrolytes (e.g., EC/DMC + LiPF₆) at 0.5–5 wt% to form a stable SEI layer in situ |
Manufacturing Quality Control of 1-ETHYL-3-METHYLIMIDAZOLIUM P-TOLUENESULFONATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 210-230 nm based on peak area comparison against reference standard. |
| Water Content | Karl Fischer Titration | Determines water by coulometric or volumetric titration where iodine reacts stoichiometrically with water in a methanol-based solvent system. |
| Residual Solvents | GC-FID | Identifies and quantifies volatile organic solvents (e.g., acetonitrile, methanol) using gas chromatography with flame ionization detection. |
| Heavy Metals | ICP-MS | Measures trace metal impurities (e.g., Pb, Cd, Ni, Fe) via inductively coupled plasma mass spectrometry after acid digestion. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column with suppressed conductivity detection. |
| Sulfonate Counterion Purity | Titrimetric Analysis (AgNO3) | Determines tosylate content by argentometric titration using silver nitrate and potentiometric endpoint detection. |
| Acid Value | Acid-Base Titration | Measures free acidic impurities by titration with standardized NaOH solution using phenolphthalein or potentiometric endpoint. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity of the sample against water-white standard under controlled lighting conditions. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary method per USP <741>. |
| Residue on Ignition | Gravimetric Analysis | Quantifies inorganic residue after high-temperature ashing (600-750 C) followed by precise weighing. |
| Organic Volatile Impurities | GC-MS | Screens for unknown or unexpected volatile organics using gas chromatography coupled with mass spectrometric identification. |
| Specific Optical Rotation | Polarimetry | Measures optical activity using sodium D-line light to detect chiral impurities or enantiomeric excess if applicable. |
