Industrial Applications of 1190-16-5
| Industry | Application | Process |
|---|---|---|
| Organosilicon Materials | Silane Coupling Agent Intermediate | Used to synthesize cyano-functional organosilane coupling agents; hydrolysis and condensation reactions introduce the agents onto inorganic material surfaces to improve organic–inorganic interfacial compatibility |
| Specialty Polymers | Functional Monomer | Participates in addition polymerization or condensation polymerization to produce heat-resistant, highly polar organosilicone elastomers or resins with cyano-functional side chains |
| Electronic Chemicals | Encapsulant Modifier | Added to epoxy or organosilicone encapsulants; the cyano group reacts with curing agents to enhance adhesion strength and resistance to humid-heat conditions |
| Pharmaceutical Intermediates | Silicon-Containing Heterocycle Synthesis Precursor | Undergoes Heck or Stille coupling with aryl halides under palladium catalysis to form silicon–carbon bonds, enabling synthesis of silicon-containing bioactive molecules |
Manufacturing Quality Control of 1190-16-5
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies main component peak area against calibrated standard curve using retention time matching. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Acid Value | Acid-Base Titration with NaOH standard solution | Determines acidic impurities by neutralization with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Chloride Content | Potentiometric Titration with AgNO3 | Quantifies chloride ions by precipitation titration using silver nitrate and silver indicator electrode. |
| Residue on Ignition | Gravimetric Analysis after High-Temperature Ashing | Measures non-volatile inorganic residue mass after combustion at 550-600 C in muffle furnace. |
| Color | Visual Comparison or Spectrophotometry (APHA/Pt-Co Scale) | Evaluates color intensity by matching sample to standardized platinum-cobalt solutions or measuring absorbance at 455 nm. |
| Density | Digital Density Meter or Pycnometer | Determines mass per unit volume at specified temperature (e.g., 20 C) using oscillating U-tube principle or calibrated glass vessel. |
| Refractive Index | Refractometry | Measures bending of light through sample at controlled temperature to determine purity and consistency. |
| Heavy Metals (as Pb) | ICP-OES | Quantifies total heavy metal content after acid digestion by plasma-excited atomic emission spectroscopy. |
| Residual Solvents (e.g., hexane, toluene) | Gas Chromatography (GC) with Headspace Sampling | Separates and quantifies volatile solvents based on partitioning into headspace and thermal desorption. |
| Alkali Metals (Na, K) | ICP-OES | Measures trace alkali metals post-acid digestion using element-specific emission wavelengths in argon plasma. |
| Non-Volatile Matter | Gravimetric Analysis after Solvent Evaporation | Determines residue mass after controlled evaporation of a known sample mass under nitrogen stream at 105 C. |
