Industrial Applications of 1631-83-0
| Industry | Application | Process |
|---|---|---|
| Organosilicon Materials | Monomer for synthesizing silicone rubber and silicone resins | Used as a crosslinker or comonomer in hydrolysis-condensation reactions to produce heat- and weather-resistant organosilicon polymers |
| Chemical Intermediates | Starting material for synthesizing organosilicon compounds | Processed via hydrolysis, alcoholysis, or ammonolysis to produce intermediates such as diphenylsilanediol and diphenylsilane derivatives |
| Coatings & Paints | Component of high-temperature-resistant coatings | Blended with other silane coupling agents to modify metal or ceramic surface coatings, enhancing adhesion and thermal stability |
| Electronics & Electrical | Modifier for encapsulation materials | Incorporated into silicone encapsulation resins for semiconductor or LED packaging to improve electrical insulation and thermal resistance |
| Plastic Additives | Improves filler dispersion | Acts as a silane coupling agent to enhance interfacial compatibility and dispersion of inorganic fillers (e.g., silica) in silicone plastics |
Manufacturing Quality Control of 1631-83-0
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) | Quantifies chlorodiphenylsilane peak area relative to calibration standards using a flame ionization detector. |
| Moisture Content | Karl Fischer Titration | Measures water content via coulometric or volumetric titration with iodine generated electrochemically or added stoichiometrically. |
| Acid Number | Acid-Base Titration | Determines acidic impurities by titration with standardized potassium hydroxide solution using phenolphthalein indicator. |
| Residue on Evaporation | Gravimetric Analysis | Measures non-volatile residue after controlled evaporation under inert atmosphere and subsequent weighing. |
| Chloride Ion Content | Potentiometric Titration | Quantifies free chloride using silver nitrate titrant and silver/silver chloride reference electrode. |
| Heavy Metals (Pb, Fe, Cu, Ni) | ICP-OES | Simultaneously detects trace metal impurities after acid digestion by measuring element-specific atomic emission intensities. |
| Phenyl Content | Elemental Analysis (CHN) | Determines carbon and hydrogen mass percentages; phenyl group content inferred from stoichiometric calculation. |
| Volatility Loss | Thermogravimetric Analysis (TGA) | Measures mass loss under controlled heating to assess low-boiling impurities or decomposition onset. |
| Color | APHA Color Scale (Visual or Spectrophotometric) | Compares sample color to platinum-cobalt standard solutions or measures absorbance at 455 nm. |
| Density | Digital Density Meter | Determines mass per unit volume at specified temperature using oscillating U-tube principle. |
| Refractive Index | Refractometry | Measures bending of light through liquid sample at 20 C to infer purity and composition. |
| Non-Volatile Matter | Hot Filtration and Gravimetry | Filters hot sample through pre-weighed membrane, dries residue, and weighs to determine insoluble particulates. |
