Manufacturing Quality Control of Diphenyldiethoxysilane
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) | Quantifies main component using retention time and peak area against calibrated standard. |
| Moisture Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration with iodine-based reagent. |
| Acid Value | Acid-Base Titration | Determines acidic impurities by titration with standardized KOH solution in alcoholic medium. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Evaluates yellowness by matching sample color to APHA platinum-cobalt standards. |
| Density at 20 C | Digital Density Meter | Measures mass per unit volume using oscillating U-tube principle. |
| Refractive Index at 20 C | Refractometry | Determines ratio of light velocity in air vs. sample using critical angle measurement. |
| Residue on Evaporation | Gravimetric Analysis | Weighs non-volatile residue after controlled evaporation under specified conditions. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Measures total heavy metals after wet digestion by atomic absorption at characteristic wavelength. |
| Iron Content | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Quantifies Fe after acid digestion by detecting element-specific emission lines. |
| Ethoxy Group Content | Hydrolysis-GC or Titration | Determines ethoxy groups via acid-catalyzed cleavage followed by GC analysis or back-titration. |
| Volatile Impurities | Headspace Gas Chromatography (HS-GC) | Detects low-boiling impurities by analyzing vapor phase above heated sample. |
