Industrial Applications of Ethylene carbonate
| Industry | Application | Process |
|---|---|---|
| Lithium-ion batteries | Electrolyte solvent | Mixed with dimethyl carbonate, ethyl methyl carbonate, and other solvents for lithium-ion battery electrolyte systems to enhance ionic conductivity and stability |
| Chemical synthesis | Organic intermediate | Used to synthesize polycarbonate polyols, nonionic surfactants, lubricants, and pharmaceutical intermediates (e.g., tenofovir) |
| Gas treatment | CO₂ absorbent | Employed as an efficient, regenerable physical solvent for CO₂ removal in gas purification processes |
| Plastics industry | Polycarbonate monomer | Acts as a cyclic carbonate monomer in ring-opening polymerization to produce aliphatic polycarbonate materials |
| Textile dyeing and printing | Fiber treatment auxiliary | Used as a swelling agent and modifier for cellulose fibers to improve dyeability and fiber softness |
Manufacturing Quality Control of Ethylene carbonate
| Detection Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe sample color and transparency under natural light or standard illumination; determine whether it is a colorless transparent liquid, and check for suspended particles or impurities. |
| Colorimetry (Color) | Platinum-Cobalt Colorimetric Method (GB/T 3143) | Compare the sample with platinum-cobalt standard color scales to quantitatively assess color intensity, used to control product purity and oxidation level. |
| Purity | Gas Chromatography (GC) | Use capillary column gas chromatography with flame ionization detection (FID); identify components by retention time and quantify total purity using area normalization method. |
| Moisture Content | Karl Fischer Titration | Determine trace moisture in samples via electrochemical titration principle, available in volumetric or coulometric modes, suitable for ppm-level moisture detection. |
| Acid Value (Acidity) | Acid-Base Titration | Titrate free acids in the sample using standardized potassium hydroxide in ethanol solution; express results as milligrams of KOH required to neutralize one gram of sample (mg KOH/g). |
| Density | Density Meter Method or Specific Gravity Bottle Method | Measure mass per unit volume at a specified temperature (e.g., 20°C), used to verify material consistency and purity. |
| Refractive Index | Refractometry (Abbe Refractometer) | Determine refractive index under specific conditions (e.g., 20°C) for sodium D-line (589 nm), used for auxiliary identification and purity assessment. |
| Electrical Conductivity | Conductivity Meter Method | Measure conductivity of the sample at a given temperature to reflect ionic impurity levels, commonly applied in battery-grade ethylene carbonate control. |
| Heavy Metal Impurities | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) or Atomic Absorption Spectroscopy (AAS) | Quantitatively detect metal ions such as Na, K, Fe, Cu, ensuring compliance with electronic-grade or battery-grade material specifications. |
| Ethylene Oxide Residue | Gas Chromatography (GC) | Use headspace sampling-GC/FID to detect residual ethylene oxide from synthesis processes, ensuring product safety. |
| Particulate Matter Content | Particle Counting (Laser Particle Analysis) | Detect the number of particles ≥0.5 μm or ≥1.0 μm using a liquid particle counter, critical for high-purity reagents (e.g., raw materials for lithium-ion battery electrolytes). |
