Industrial Applications of 18162-82-8
| Industry | Application | Process |
|---|---|---|
| Organic Synthesis | Silyl protecting reagent for selective protection of alcohol and phenol hydroxyl groups | Reacted with alcohols or phenols in anhydrous inert solvents (e.g., THF, DCM) in the presence of a base (e.g., NaH, Et₃N) to yield chloromethyl ether silyl-protected products |
| Materials Science | Precursor for organic–inorganic hybrid materials, used in the preparation of functional mesoporous silica | Copolymerized with a template agent as a silicon source; hydrolysis–condensation forms Si–O–Si networks, followed by template removal to yield ordered mesoporous structures |
| Surface Treatment | Intermediate for silane coupling agents, used to modify the surface of inorganic fillers | Undergoes hydrolysis–condensation with hydroxyl-bearing inorganic materials (e.g., SiO₂, Al₂O₃) to introduce reactive chloromethyl groups onto the surface, enabling subsequent amidation or azidation |
Manufacturing Quality Control of 18162-82-8
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) | Quantifies main component by separation and peak area comparison against certified reference standard. |
| Chloride Content | Potentiometric Titration with AgNO3 | Measures chloride ions via argentometric titration using silver nitrate and silver indicator electrode. |
| Acid Value | Acid-Base Titration with NaOH | Determines acidic impurities by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Water Content | Karl Fischer Coulometric Titration | Electrochemically quantifies water based on iodine generation proportional to water content in sample. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after controlled high-temperature ashing and weighing. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Simultaneously detects trace heavy metals by ionization in plasma and mass spectrometric detection. |
| Iron Content | ICP-OES | Quantifies iron by measuring atomic emission intensity at characteristic wavelength after plasma excitation. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Evaluates yellowness by matching sample color to APHA platinum-cobalt standard scale. |
| Density at 20 C | Digital Density Meter | Determines mass per unit volume using oscillating U-tube principle with temperature control. |
| Refractive Index at 20 C | Abbe Refractometer | Measures light bending angle at air-sample interface to infer molecular composition and purity. |
| Volatility Loss (105 C, 2 h) | Thermogravimetric Analysis (TGA) | Quantifies weight loss under controlled heating to assess low-boiling impurities and stability. |
| Free Silanol Content | 1H NMR Spectroscopy | Detects Si-OH protons by integration of characteristic chemical shift region relative to internal standard. |
