Industrial Applications of Vinylene carbonate
| Industry | Application | Process |
|---|---|---|
| Battery Manufacturing | As an electrolyte additive for lithium-ion batteries | Mixed with other solvents and additives in the electrolyte |
| Organic Synthesis | As an organic synthesis intermediate | Used to synthesize other compounds containing cyclic carbonate structures |
| Polymer Materials | For the production of polymer materials such as polycarbonates | Converted into corresponding polymer materials via polymerization |
Manufacturing Quality Control of Vinylene carbonate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (VC content) | HPLC-UV | Quantifies VC concentration using reversed-phase HPLC with UV detection at 210 nm based on peak area calibration 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. |
| Acidity (as HCl) | Acid-base titration | Measures acidic impurities via potentiometric or visual titration with standardized NaOH solution using phenolphthalein or pH endpoint detection. |
| Residue on ignition | Gravimetric analysis | Evaluates non-volatile inorganic residue after controlled high-temperature ashing and subsequent weighing of the cooled crucible. |
| Heavy metals (Pb, Cd, Hg, As) | ICP-MS | Simultaneously quantifies trace heavy metals after acid digestion using inductively coupled plasma mass spectrometry with isotope dilution or external calibration. |
| Chloride content | Ion chromatography | Separates and quantifies chloride ions using anion-exchange column with suppressed conductivity detection and sodium carbonate/bicarbonate eluent. |
| Appearance | Visual inspection | Assesses physical state, color, and clarity of sample against standard white background under controlled lighting conditions. |
| Melting point | Capillary melting point apparatus | Determines temperature range at which solid VC transitions to liquid using calibrated capillary tube method per USP <741>. |
| Residual solvents (e.g., DMF, acetone) | GC-FID | Quantifies volatile organic solvents by gas chromatography with flame ionization detection using internal standard calibration. |
| Peroxide value | Iodometric titration | Measures hydroperoxides via oxidation of iodide to iodine under acidic conditions, followed by titration with standardized sodium thiosulfate. |
| Particle size distribution | Laser diffraction | Analyzes dry or wet dispersed powder using Mie scattering theory to determine volume-based particle size distribution. |
| Bulk density | ASTM D1895 | Determines mass per unit volume of freely settled powder using a calibrated cylinder and standardized tapping procedure. |
