Manufacturing Quality Control of Tetrapropoxysilane
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies tetrapropoxysilane peak area against calibrated standard curve using retention time and response factor. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water; endpoint detected amperometrically. |
| Acidity (as HCl) | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution and potentiometric or phenolphthalein endpoint detection. |
| Color | Visual Comparison or Spectrophotometry (APHA/Pt-Co scale) | Compares sample color to platinum-cobalt standard solutions or measures absorbance at 455 nm in a 10-mm cell. |
| Density | Digital Density Meter (Oscillating U-tube) | Measures oscillation period of a U-shaped tube filled with sample; density calculated from calibration curve. |
| Refractive Index | Abbe Refractometer | Determines refractive index by measuring critical angle of total internal reflection at prism-sample interface. |
| Non-Volatile Residue | Gravimetric Analysis (Evaporation and Weighing) | Evaporates known mass of sample under controlled conditions and weighs residual solids after drying. |
| Iron (Fe) Content | ICP-OES | Atomizes and excites sample in argon plasma; quantifies Fe by measuring characteristic emission intensity at specific wavelength. |
| Aluminum (Al) Content | ICP-OES | Atomizes and excites sample in argon plasma; quantifies Al by measuring characteristic emission intensity at specific wavelength. |
| Chloride (Cl-) Content | Ion Chromatography (IC) with Conductivity Detection | Separates anions on ion-exchange column; detects Cl- based on electrical conductivity of eluted species. |
| Propyl Alcohol (Impurity) | Gas Chromatography (GC) with FID detector | Separates and quantifies residual propyl alcohol using external calibration and same GC conditions as assay method. |
| Appearance (Clarity) | Visual Inspection in Glass Cell | Observes sample in clear, colorless glass container against white background and adequate lighting for particulates or haze. |
