Industrial Applications of 78-71-7
| Industry | Application | Process |
|---|---|---|
| Polymers | Monomer for synthesizing polyether polyols | Ring-opening polymerization to produce epoxy resins or polyurethane prepolymers with high crosslink density and superior heat resistance |
| Coatings & Adhesives | Reactive diluent for modifying epoxy resins | Copolymerizes with epoxy groups to reduce system viscosity while enhancing flexibility and adhesion of cured products |
| Electronics & Electrical | Component in encapsulation and insulating materials | Acts as a crosslinker in thermosetting resin systems to improve dielectric properties and resistance to humidity and thermal cycling |
| Pharmaceutical Intermediates | Precursor for synthesizing oxygen-containing heterocyclic drugs | Constructs complex heterocyclic frameworks via nucleophilic substitution or reduction reactions (side reactions must be strictly controlled) |
Manufacturing Quality Control of 78-71-7
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component peak area relative to calibrated standard using flame ionization detection. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration with iodine-based reagent reacting stoichiometrically with water. |
| Acidity (as HCl) | Acid-Base Titration with NaOH | Neutralizes acidic impurities (e.g., HCl) using standardized sodium hydroxide solution and potentiometric endpoint detection. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic residue after high-temperature ashing and weighing. |
| Chloride Ion (Cl-) | Ion Chromatography (IC) | Separates and quantifies chloride anions using anion-exchange column and conductivity detection. |
| Heavy Metals (Pb, Cd, Hg, Cr) | ICP-OES | Atomizes and excites sample in plasma; measures characteristic emission wavelengths for multi-element quantification. |
| Color | APHA Color Scale (Visual or Spectrophotometric) | Compares sample color to platinum-cobalt standard solutions using visual match or spectrophotometric absorbance at 455 nm. |
| Density | Digital Density Meter | Measures mass per unit volume at specified temperature using oscillating U-tube principle. |
| Refractive Index | Refractometry | Determines ratio of light velocity in air vs. sample using critical angle measurement of monochromatic light. |
| Volatility Loss | Thermogravimetric Analysis (TGA) | Measures mass loss under controlled heating to assess volatile content and thermal stability. |
| Aldehyde Impurities | HPLC with UV Detection | Separates and quantifies low-level aldehyde impurities using reverse-phase column and UV absorbance detection. |
| Peroxide Value | Iodometric Titration | Measures peroxides by reaction with potassium iodide under acidic conditions, followed by titration of liberated iodine with sodium thiosulfate. |
