Manufacturing Quality Control of Bis[3-(triethoxysilyl)propyl]tetrasulfide
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color and physical state. Qualified products are typically colorless to pale yellow transparent liquids, free from suspended particles or precipitates. |
| Density | Density Meter Method / Specific Gravity Bottle Method | Determine the mass-to-volume ratio under specified temperature (e.g., 25°C) to assess purity and batch consistency. |
| Refractive Index (n20D) | Abbe Refractometer Method | Measure refractive index at 20°C as an auxiliary indicator of purity and composition. |
| Purity (Main Component Content) | Gas Chromatography (GC) | Use capillary column gas chromatography to quantify the main component by comparison with standard reference materials or normalization method, commonly used for quantitative analysis. |
| Sulfur Content | Ultraviolet Fluorescence Method or Oxygen Bomb Combustion-Titration Method | High-temperature combustion of the sample releases sulfur as SO₂, which is then detected via ultraviolet fluorescence or absorption titration to determine total sulfur content. |
| Ethoxy Group Content | Hydrolysis-Titration Method | After hydrolysis, ethanol is released from the sample; it is distilled and quantified via acid-base titration to indirectly assess structural integrity. |
| Hydrolytic Stability | Hydrolysis Test + Turbidity/Precipitation Observation | Dissolve the sample in a water-containing solvent and observe changes in clarity over time to evaluate stability under humid conditions. |
| pH Value (Diluted Solution) | pH Meter Measurement | Dilute the sample in deionized water according to a specified ratio, then measure acidity/alkalinity using a pH meter to detect potential acidic by-products. |
| Volatiles (Volatile Substances) | Thermogravimetric Analysis (TGA) or Oven Weight Loss Method | Heat the sample at a specified temperature for a set duration and measure mass loss to assess volatile impurities or residual solvents. |
| Infrared Spectroscopy (IR) | Fourier Transform Infrared Spectroscopy (FT-IR) | Perform infrared scanning on the sample and compare with standard spectra to confirm the presence of functional groups (e.g., Si-O-C, S-S). |
