Manufacturing Quality Control of (3-bromopropyl)triethoxysilane
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component by retention time and peak area against calibrated standard. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration using iodine-sulfur dioxide reaction. |
| Acid Number | Acid-Base Titration with NaOH | Determines acidic impurities by titration with standardized sodium hydroxide solution. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing and weighing. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Evaluates yellowness by matching sample color to APHA platinum-cobalt standards. |
| Density at 20 C | Digital Density Meter | Determines mass per unit volume using oscillating U-tube principle. |
| Refractive Index at 20 C | Refractometry | Measures bending of light through sample to infer purity and composition. |
| Volatility Loss | Thermogravimetric Analysis (TGA) | Quantifies weight loss under controlled heating to assess volatile impurities. |
| Heavy Metals (as Pb) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Detects trace metals by atomization and emission intensity measurement at element-specific wavelengths. |
| Residual Solvents | Gas Chromatography (GC) with Headspace Sampling | Identifies and quantifies low-boiling solvents using equilibrium vapor phase analysis. |
| Hydrolytic Stability | pH Monitoring over Time | Measures pH change in aqueous emulsion to assess rate of silane hydrolysis and acid generation. |
