Industrial Applications of VINYLDIPHENYLMETHYLSILANE
| Industry | Application | Process |
|---|---|---|
| Organic Synthesis | Used as a silyl protecting group or reagent for functional group introduction | Participates in carbon–silicon bond formation in Grignard reactions, palladium-catalyzed couplings, and related transformations |
| Polymer Materials | Used to synthesize silicon-containing functional polymers or crosslinkers | Introduces vinyl and phenyl moieties via free-radical polymerization or condensation polymerization to enhance thermal stability or hydrophobicity |
| Electronic Chemicals | Used as a precursor for organic silicon dielectric or encapsulation materials | Forms thin films via chemical vapor deposition (CVD) or solution-based coating processes |
| Pharmaceutical Intermediates | Used to synthesize silicon-containing drug molecules or bioactive probes | Constructs target molecular frameworks via hydrosilylation or cross-coupling reactions |
Manufacturing Quality Control of VINYLDIPHENYLMETHYLSILANE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies vinyl group content by separation and flame ionization detection relative to internal standard. |
| Vinyl Content | 1H NMR Spectroscopy | Measures integral ratio of vinyl protons (4.8-6.5 ppm) to reference protons (e.g., phenyl or methyl) for stoichiometric calculation. |
| Acid Number | Acid-Base Titration with KOH in isopropanol | Determines free acidic impurities by titration with standardized potassium hydroxide solution using phenolphthalein indicator. |
| Water Content | Karl Fischer Coulometric Titration | Electrochemically quantifies trace water via iodine generation and stoichiometric reaction with water in anhydrous medium. |
| Density at 20 C | Digital Density Meter (Oscillating U-tube) | Measures sample density based on resonant frequency shift of a vibrating U-shaped tube filled with liquid. |
| Refractive Index at 20 C | Abbe Refractometer | Determines refractive index by measuring critical angle of total internal reflection at prism-sample interface. |
| Color (APHA) | Visual Comparison or Spectrophotometric APHA Scale | Evaluates yellowness intensity by matching sample color to platinum-cobalt standard solutions or measuring absorbance at 455 nm. |
| Residue on Evaporation | Gravimetric Analysis (Weight Loss on Drying) | Measures non-volatile residue after controlled evaporation under nitrogen and drying to constant weight. |
| Chloride Content | Ion Chromatography (IC) with Conductivity Detection | Separates and quantifies chloride ions using anion-exchange column and suppressed conductivity detection. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) after wet digestion | Quantifies total heavy metals after acid digestion by measuring atomic absorption of lead at 283.3 nm. |
| Volatile Impurities | Headspace Gas Chromatography-Mass Spectrometry (HS-GC-MS) | Identifies and quantifies low-boiling impurities by thermal equilibration in headspace vial followed by GC separation and MS detection. |
| Viscosity at 25 C | Rotational Viscometer (Brookfield type) | Measures resistance to flow under controlled shear rate using spindle rotation in sample at constant temperature. |
