Industrial Applications of Diethylene Glycol Dimethyl Ether
| Industry | Application | Process |
|---|---|---|
| Lithium-ion batteries | Electrolyte solvent | Mixed with lithium salts (e.g., LiPF₆) and other solvents (e.g., ethylene carbonate) to formulate electrolytes, enhancing ionic conductivity and electrode interfacial stability |
| Organic synthesis | Reaction solvent | Used in Grignard reactions, lithiation reactions, and coupling reactions (e.g., Heck, Suzuki), owing to its high boiling point, strong solvating power, and excellent stability toward alkali metal reagents |
| Electronic chemicals | Component of cleaning agents | Employed as a high-purity solvent for removal of photoresist residues and metal-organic precursors in semiconductor manufacturing |
| Pharmaceutical intermediate synthesis | Solvent for extraction and recrystallization | Applied in the separation and purification of active pharmaceutical ingredients (e.g., antibiotics, anticancer agents), leveraging its partial miscibility with water and good thermal stability |
| Polymer materials | Reaction medium for polymerization | Used as a solvent in anionic polymerization (e.g., of butadiene or isoprene) to control polymerization rate and molecular weight distribution |
Manufacturing Quality Control of Diethylene Glycol Dimethyl Ether
| Test Item | Common Test Method | Method Overview |
|---|---|---|
| Purity | Gas Chromatography (GC) | Using capillary column gas chromatography, the content of diethylene glycol dimethyl ether is determined by comparing retention times with standard substances and quantifying via peak area normalization or internal standard method, to evaluate its purity. |
| Moisture | Karl Fischer Titration | Utilizes the quantitative reaction between Karl Fischer reagent and water in the sample. The moisture content is measured by coulometric or volumetric titration, suitable for trace moisture detection. |
| Acid Value | Acid-Base Titration | The sample is dissolved in neutral ethanol or isopropanol, phenolphthalein is used as indicator, and titrated with standardized potassium hydroxide solution. The acid value is expressed as milligrams of KOH required to neutralize 1 g of sample, indicating the level of acidic impurities. |
| Color | Platinum-Cobalt Colorimetry (Hazen Method) | The sample is placed in a colorimeter tube and compared visually or using a colorimeter against a series of standard platinum-cobalt solutions. The color intensity is reported in Hazen units. |
| Density | Densitometer or Oscillating U-tube Method | The density of the sample is measured at a specified temperature (typically 20°C) using either a glass hydrometer or digital oscillating U-tube densitometer, used to assess product consistency and influence of impurities. |
| Refractive Index | Abbe Refractometry | The refractive index of the sample for sodium light (589.3 nm) is measured under constant temperature (e.g., 20°C) using an Abbe refractometer, serving as an auxiliary parameter for identification and purity control. |
| Volatiles Residue / Evaporation Residue | Gravimetric Method | A known quantity of sample is evaporated to dryness under specified conditions, and the residue is weighed. The percentage of residue indicates the presence of high-boiling impurities or non-volatile substances. |
| Peroxides | Iodometric Method or Colorimetric Method | The sample reacts with potassium iodide to liberate iodine, which is then titrated with sodium thiosulfate (iodometric method), or detected via a color-forming reaction (colorimetric method), used to evaluate peroxide formation during storage. |
