| Industry | Application | Process |
|---|---|---|
| Chemicals | Organic synthesis intermediate | Used in the synthesis of polyphenylene oxide (PPO/PPE) engineering plastics, fragrances, and pharmaceuticals |
| Fragrances | Fixative | Applied as a fragrance-stabilizing component in perfumes and cosmetics |
| Pesticides | Insecticide/fungicide intermediate | Used in the synthesis of certain ether-containing agrochemicals |
| Heat transfer | High-temperature heat transfer fluid component | Mixed with biphenyl to form a eutectic mixture (e.g., Dowtherm A) for industrial heat transfer systems |
| Polymers | Monomer or modifier in polymerization | Participates in the production of high-temperature-resistant, high-dielectric-strength polymer materials |
| Detection Item | Common Detection Methods | Method Overview |
|---|---|---|
| Content Determination | Gas Chromatography (GC) | Separation is performed using a capillary column, and detection is carried out with a flame ionization detector (FID). Quantification of diphenyl ether is achieved via external or internal standard methods, featuring high sensitivity and excellent reproducibility. |
| Purity Analysis | High-Performance Liquid Chromatography (HPLC) | A C18 reversed-phase column is used with a mobile phase such as methanol-water, and detection is performed using a UV detector (approximately 254 nm). This method effectively separates impurities and calculates the purity of diphenyl ether. |
| Volatile Impurity Detection | Gas Chromatography-Mass Spectrometry (GC-MS) | Combines the separation capability of gas chromatography with the qualitative power of mass spectrometry to identify and detect volatile organic impurities or residual solvents in diphenyl ether. |
| Water Content | Karl Fischer Titration | Based on the reaction of iodine and sulfur dioxide with water in an anhydrous environment, this method precisely measures trace amounts of water in samples, making it suitable for quality control of moisture-sensitive materials. |
| Acid Value/Acidity | Acid-Base Titration | The sample is dissolved in ethanol or isopropanol and titrated with a standard sodium hydroxide solution to determine the content of free acids, evaluating the level of acidic impurities in diphenyl ether. |
| Color | Visual Color Comparison or Spectrophotometry | The sample solution is compared visually with standard color scales, or its absorbance is measured at a specific wavelength (e.g., 420 nm) to assess whether the product's color meets industrial or reagent-grade requirements. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | After sample digestion, residual heavy metals such as lead, arsenic, and mercury are detected to ensure compliance with safety and environmental standards. |
| Residual Solvents | Headspace-Gas Chromatography (HS-GC) | By heating the headspace vial of the sample, residual solvents volatilize and are then analyzed for common solvents such as benzene, toluene, and dichloromethane, complying with pharmacopeial or environmental regulations. |
