Manufacturing Quality Control of DIETHYLPHOSPHATOETHYLTRIETHOXYSILANE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component peak area relative to calibrated standard using flame ionization detection. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between iodine, sulfur dioxide, and water in pyridine/methanol medium. |
| Acid Value | Acid-Base Titration with NaOH | Determines free acidic impurities by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Color | Visual Comparison or Spectrophotometry (APHA/Pt-Co scale) | Evaluates yellowness intensity by matching sample color to standardized platinum-cobalt solutions or measuring absorbance at 430 nm. |
| Density at 25 C | Digital Density Meter | Measures mass per unit volume using oscillating U-tube principle with temperature control. |
| Refractive Index at 20 C | Refractometry | Determines ratio of light velocity in air versus sample using critical angle measurement at specified wavelength (e.g., 589 nm). |
| Chloride Content | Ion Chromatography (IC) or Potentiometric Titration | Separates and quantifies chloride ions via conductivity detection (IC) or silver nitrate titration with chloride-selective electrode. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after controlled high-temperature ashing and weighing. |
| Heavy Metals (Pb, Cd, Hg, Cr) | ICP-OES | Quantifies trace metal elements by measuring characteristic atomic emission intensities after microwave-assisted acid digestion. |
| Phosphorus Content | UV-Vis Spectrophotometry (Ammonium Molybdate method) | Measures phosphomolybdate complex absorbance at ~820 nm after oxidation and complex formation. |
| Ethoxy Group Content | Hydrolysis-Gas Chromatography | Determines ethoxy groups via acid-catalyzed cleavage followed by GC analysis of released ethanol. |
| Viscosity at 25 C | Rotational Viscometry | Measures resistance to flow under shear stress using a calibrated spindle rotating at defined speed and temperature. |
