Industrial Applications of 4-VINYLBIPHENYL
| Industry | Application | Process |
|---|---|---|
| Polymers | Used as a comonomer in the synthesis of heat-resistant and oxidation-resistant specialty engineering plastics (e.g., polyarylates, polyimide precursors) | Copolymerized with monomers such as bisphenols and dicarboxylic acids via free-radical polymerization or condensation polymerization |
| Liquid Crystals | Employed as a rigid mesogenic core unit in liquid crystal monomers to enhance clearing point and optical anisotropy | Integrated into side chains via Suzuki or Heck coupling, followed by purification to formulate liquid crystal mixtures |
| Organic Optoelectronic Materials | Serves as a building block for OLED hole-transport layers (HTL) or host materials, improving charge-carrier mobility and thermal stability | Participates in palladium-catalyzed cross-coupling reactions to construct multi-aryl conjugated frameworks, subsequently processed into thin films by spin-coating |
| Pharmaceutical Intermediates | Used in synthesizing biphenyl derivatives with anti-inflammatory and antitumor activity (e.g., analogues of selective COX-2 inhibitors) | Subjected to functional-group transformations—such as bromination, borylation, or nitration—prior to palladium-catalyzed coupling to assemble target molecules |
Manufacturing Quality Control of 4-VINYLBIPHENYL
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantitative determination based on peak area comparison against certified reference standard using capillary column separation. |
| Water Content | Karl Fischer Titration | Electrochemical titration measuring water via iodine-sulfur dioxide reaction in methanol-based solvent. |
| Residue on Ignition | Gravimetric Analysis | Mass of non-volatile residue determined after high-temperature ashing at 750 C in a muffle furnace. |
| Color | APHA Color Scale (Visual or Spectrophotometric) | Comparison of sample solution color intensity to platinum-cobalt standards using spectrophotometer at 455 nm. |
| Acidity (as H2SO4) | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals after acid digestion by measuring absorbance of ground-state atoms at characteristic wavelength. |
| Chlorinated Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Identification and quantification of chlorinated by-products based on retention time and mass spectral fragmentation patterns. |
| Refractive Index | Refractometry | Measurement of light bending angle at air-sample interface using calibrated digital refractometer at 20 C. |
| Specific Gravity | Pycnometry | Density determination by comparing mass of known volume of sample to mass of same volume of water at 20 C. |
| Non-Volatile Residue | Evaporation Gravimetry | Mass of residue remaining after gentle evaporation of fixed sample volume under controlled nitrogen flow and drying. |
| Aldehyde Impurities | HPLC with UV Detection | Separation and quantification of aldehyde impurities using reversed-phase column and UV detection at 260 nm. |
| Sulfated Ash | Gravimetric Analysis | Mass of sulfate-containing ash after combustion with sulfuric acid pretreatment and heating to constant weight at 750 C. |
