Industrial Applications of Divinylbenzene
| Industry | Application | Process |
|---|---|---|
| Chemical | Production of crosslinked polystyrene resins | Used as a crosslinking agent in copolymerization with styrene to form a three-dimensional network structure |
| Water Treatment | Preparation of ion exchange resins | Applied in the synthesis of styrene–divinylbenzene copolymers as the structural backbone material |
| Pharmaceutical | Preparation of drug carriers and separation media | Employed as a crosslinked matrix for chromatographic packing materials and solid-phase synthesis supports |
| Materials Science | Synthesis of polymeric microspheres and functional materials | Used in emulsion or suspension polymerization to prepare monodisperse microspheres |
| Electronics | Component of encapsulation and insulating materials | Utilized as a crosslinking monomer in thermally stable polymeric materials |
| Environmental Protection | Preparation of adsorbents and solid-phase extraction materials | Applied in the synthesis of macroporous adsorption resins for enrichment and separation of organic compounds |
Manufacturing Quality Control of Divinylbenzene
| Test Item | Common Test Method | Method Overview |
|---|---|---|
| Purity Analysis | Gas Chromatography (GC) | Uses a capillary gas chromatographic column for separation and a flame ionization detector (FID) for detection. Components in DVB (such as monomers, isomers, and impurities) are identified by retention time and quantified using peak area normalization or external standard methods, enabling accurate determination of composition. |
| Moisture Content | Karl Fischer Titration | Quantitatively determines water content in the sample based on an electrochemical reaction. Available in coulometric (for trace water) and volumetric (for higher water content) modes. Suitable for precise measurement of trace moisture in DVB. |
| Density | Density Meter / Pycnometer Method | Measures liquid density at a specified temperature (e.g., 20°C) using a pycnometer or digital density meter to assess batch-to-batch consistency. |
| Color | Platinum-Cobalt Colorimetric Method (APHA Color) | Compares the sample visually or instrumentally against standard platinum-cobalt solutions to evaluate color intensity, indicating levels of impurities or degree of oxidation. |
| Acid Value (Acidity) | Acid-Base Titration | Titrates free acids in the sample with a standardized potassium hydroxide ethanol solution. Expressed as milligrams of KOH required to neutralize one gram of sample (mg KOH/g), used to monitor acidic impurities formed during storage. |
| Peroxide Content | Iodometric Method | In acidic conditions, peroxides oxidize iodide ions to release iodine, which is then titrated with a standardized sodium thiosulfate solution. This indirect method measures peroxide content to evaluate storage stability. |
| Volatile Impurities | Headspace Gas Chromatography (HS-GC) | The sample is placed in a sealed container and heated to equilibrium; the vapor phase above the sample is then injected for analysis. Suitable for detecting residual solvents or low-boiling-point impurities. |
| Isomer Ratio | Gas Chromatography-Mass Spectrometry (GC-MS) | Combines the separation capability of GC with the identification power of MS to accurately identify and quantify different isomers in DVB (e.g., meta- and para-divinylbenzene). |
