Industrial Applications of 766-77-8
| Industry | Application | Process |
|---|---|---|
| Chemical Synthesis | Intermediate for Silane Coupling Agents | Used to synthesize phenyl-functional silane coupling agents, enhancing interfacial adhesion between organic polymers and inorganic fillers. |
| Electronics & Electrical | Additive for Encapsulants | Incorporated into organosilicon encapsulants to improve refractive index, thermal stability, and radiation resistance via the phenyl group. |
| Polymeric Materials | Modifier for Silicone Rubber and Resins | Phenyl groups are introduced via hydrolysis-condensation to produce high-temperature-resistant silicone rubber with low compression set and highly transparent resins. |
| Pharmaceutical Chemicals | Pharmaceutical Intermediate | Serves as an organosilicon reagent in organic synthesis for constructing silicon-containing drug molecules or as a protecting group in specific reactions. |
| Laboratory Reagents | Starting Material for Grignard Reactions | Used as a precursor to Grignard reagents in laboratory research for synthesizing phenyl-substituted silane derivatives. |
Manufacturing Quality Control of 766-77-8
| Test Item | Common Testing Method | Method Description |
|---|---|---|
| Appearance | Visual Inspection | Place the sample in a colorless transparent glass bottle and observe its color and clarity under natural light or standard light source. |
| Color | Platinum-Cobalt Colorimetry (GB/T 3143) | Use standard platinum-cobalt solution for color comparison to determine the depth of color in liquid samples, commonly used to assess impurity content. |
| Purity (Main Component Content) | Gas Chromatography (GC) | Separate components using a capillary column and detect with a flame ionization detector (FID). Quantify xylene isomer content by peak area normalization or external standard method. |
| Moisture | Karl Fischer Titration | Iodine reacts quantitatively with water in the presence of sulfur dioxide, pyridine, and methanol to determine trace moisture in the sample. |
| Density | Densitometer Method or Oscillating Tube Densitometry | Measure the sample density at specified temperature (e.g., 20°C) using a hydrometer or digital densitometer for quality consistency assessment. |
| Boiling Range (Distillation Range) | Distillation Test Method (GB/T 7534) | Heat the sample in a distillation apparatus and record initial boiling point and dry point temperatures to judge volatility impurities and composition uniformity. |
| Total Impurity Content | Gas Chromatography (GC) | In GC analysis, the sum of all peak areas except the main peak represents total impurities, commonly used for quality control of high-purity reagents. |
| Sulfur Content | Ultraviolet Fluorescence Method or Microcoulometry | The sample is combusted to generate SO₂, which is then quantified by ultraviolet fluorescence detection or microcoulometric titration for low-sulfur product control. |
| Benzene Content | Gas Chromatography-Mass Spectrometry (GC-MS) | Utilize GC-MS for high selectivity separation and identification of trace benzene, avoiding interference for safety and environmental indicator testing. |
