Manufacturing Quality Control of Tetraethylene glycol dimethyl ether
| Test Item | Common Test Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color and state under natural light or standard illumination; it should be a colorless, transparent liquid with no suspended particles or sediment. |
| Color | Platinum-Cobalt Colorimetric Method (GB/T 3143 or ASTM D1209) | Compare against standard platinum-cobalt solutions to determine the color value of the sample, assessing product purity and degree of oxidation or impurity contamination. |
| Density | Densitometer / Digital Density Meter (ASTM D4052) | Measure density at a specified temperature (e.g., 20°C) to evaluate consistency in composition and detect contamination by lighter or heavier components. |
| Refractive Index | Abbe Refractometer Method (GB/T 6488 or ASTM D1218) | Determine refractive index at a specific temperature (typically 20°C), used as an auxiliary indicator for assessing purity and batch-to-batch consistency. |
| Water Content | Karl Fischer Titration (GB/T 6283 or ASTM E203) | Measure trace moisture using coulometric or volumetric methods to ensure compliance with low-moisture requirements (typically <0.1%), avoiding adverse effects on electrochemical performance. |
| Acid Value | Acid-Base Titration (GB/T 2895 or ASTM D974) | Titrate free acids using a potassium hydroxide standard solution to assess whether acidic degradation has occurred during storage or production. |
| Purity (Main Component Content) | Gas Chromatography (GC, e.g., ASTM D2710 or GB/T 11538) | Use capillary column separation with FID detection to quantify the relative percentage of tetraethylene glycol dimethyl ether; this is a key quality control parameter. |
| Boiling Range / Distillation Range | Atmospheric Distillation (GB/T 7534 or ASTM D1078) | Determine initial boiling point, dry point, and distillation temperature range to evaluate volatility and component distribution against specifications. |
| Peroxide Content | Iodometric Method or Colorimetric Method | Determine peroxide concentration via reaction with potassium iodide to generate iodine, followed by titration or colorimetry; used to evaluate oxidative stability and storage safety. |
| Heavy Metal Content | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After wet digestion, measure residual heavy metal elements such as lead, arsenic, and mercury to ensure compliance with electronic-grade or battery-grade safety standards. |
| Residual Solvents / Volatile Impurities | Headspace Gas Chromatography (HS-GC) | Analyze low-boiling organic impurities (e.g., methanol, ethanol) using headspace sampling, suitable for high-purity product control. |
