Manufacturing Quality Control of S-(Octanoyl)mercaptopropyltriethoxysilane
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) | Quantifies main component by separation and peak area comparison against certified reference standard. |
| Moisture Content | Karl Fischer Titration | Measures water content via coulometric or volumetric titration with iodine-based reagent. |
| Acid Number | Acid-Base Titration | Determines acidic impurities by titration with standardized KOH solution using phenolphthalein indicator. |
| Density at 20 C | Digital Density Meter | Measures mass per unit volume using oscillating U-tube principle calibrated with air/water standards. |
| Refractive Index at 20 C | Refractometry | Determines refractive index by measuring angle of light refraction through sample at specified temperature. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Evaluates yellowness intensity by matching to APHA color scale or measuring absorbance at 430 nm. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride ions using ion-exchange column and conductivity detection. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing and weighing. |
| Heavy Metals (as Pb) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Quantifies trace metal impurities by atomization and element-specific emission line intensity. |
| Viscosity at 25 C | Rotational Viscometry | Determines dynamic viscosity by measuring torque required to rotate spindle in sample at controlled temperature. |
| Ethoxy Group Content | Hydrolysis-Gas Chromatography | Quantifies ethoxy groups after acid-catalyzed cleavage and GC analysis of liberated ethanol. |
| Sulfur Content | Combustion-ICP-OES or Combustion-UV | Determines total sulfur by high-temperature combustion followed by detection of SO2 by UV absorption or ICP-OES. |
