Manufacturing Quality Control of Isobutylisopropyldimethoxysilane
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies main component peak area relative to internal/external standard using calibrated response factors. |
| Moisture Content | Karl Fischer Titration | Measures water content via stoichiometric reaction between water and iodine in a pyridine/methanol solvent system. |
| Acid Number | Acid-Base Titration with NaOH | Determines acidic impurities by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Residue on Evaporation | Gravimetric Analysis | Measures non-volatile residue after controlled evaporation of a known sample mass under specified temperature and time. |
| Density at 20 C | Digital Density Meter | Determines density based on oscillating U-tube principle using calibrated vibration frequency measurement. |
| Refractive Index at 20 C | Refractometry | Measures refractive index via critical angle of total internal reflection using sodium D-line light source. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement | Compares sample color to platinum-cobalt standard solutions or measures absorbance at 430 nm. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals after acid digestion by measuring atomic absorption at characteristic wavelengths. |
| Iron Content | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Determines iron concentration by measuring intensity of emitted light at specific spectral line after plasma atomization. |
| Alkoxyl Content | Acid-Catalyzed Hydrolysis followed by GC or Titration | Cleaves alkoxy groups to corresponding alcohols, then quantifies liberated methanol via GC or back-titration. |
| Volatility Loss | Thermogravimetric Analysis (TGA) | Measures mass loss under controlled heating ramp to assess low-boiling impurities and thermal stability. |
