Industrial Applications of 66604-31-7
| Industry | Application | Process |
|---|---|---|
| Organosilicon Materials | Modifier for silicone oils, silicone rubbers, and silicone resins; introduces long-chain alkyl groups to enhance hydrophobicity and lubricity | Hydrosilylation with hydride-containing silicone oils, or condensation with silanol compounds |
| Surface Treatment | Water- and soil-repellent coating agent for substrates such as metals, glass, and ceramics | Forms a hydrophobic monolayer on the substrate surface via dip-coating, spray-coating, or vapor-phase deposition |
| Textile Auxiliaries | Fabric softener and water-repellent finishing agent | Reacts with hydroxyl groups on fiber surfaces under alkaline or mildly acidic conditions to form a hydrophobic film |
| Coatings Industry | Coating additive to improve hydrophobicity, weather resistance, and leveling performance | Added directly as a functional additive to coating formulations, or pre-reacted with resins |
| Personal Care Products | Conditioning and skin-feel modifying agent in hair conditioners and skin creams | Formulated with cationic surfactants and processed into stable emulsions via emulsification |
Manufacturing Quality Control of 66604-31-7
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantitative determination based on peak area comparison against certified reference standard using capillary column separation. |
| Chloride Content | Potentiometric Titration with AgNO3 | Direct titration of chloride ions using silver nitrate solution and silver/silver sulfide indicator electrode. |
| Acid Value | Acid-Base Titration with NaOH | Neutralization of acidic impurities by standardized sodium hydroxide solution using phenolphthalein indicator. |
| Water Content | Karl Fischer Coulometric Titration | Electrochemical generation of iodine to react stoichiometrically with water; quantified via coulometric current integration. |
| Residue on Ignition | Gravimetric Analysis | Heating sample to 750 C in platinum crucible, then weighing inorganic residue after complete combustion of organic matrix. |
| Heavy Metals (Pb, Cd, Hg, Cr) | ICP-OES | Multi-element detection by measuring characteristic atomic emission intensities after plasma atomization and excitation. |
| Iron Content | Atomic Absorption Spectroscopy (AAS) | Quantification of Fe atoms by measuring absorption of specific wavelength light (248.3 nm) in acetylene-air flame. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Measurement of yellowness index at 455 nm against platinum-cobalt standard solutions in 100 mm pathlength cell. |
| Density at 20 C | Digital Density Meter | Determination via oscillating U-tube principle where resonant frequency correlates directly with sample density. |
| Refractive Index at 20 C | Abbe Refractometer | Measurement of angle of total internal reflection at prism-sample interface to calculate refractive index. |
| Volatile Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Separation by GC followed by mass spectral identification and semi-quantitation of low-boiling contaminants. |
| Silicon Content | Alkaline Fusion followed by ICP-OES | Complete decomposition by Na2CO3 fusion, dissolution, and silicon quantification via Si 251.61 nm emission line. |
