| Fine Chemicals | Synthesis of specialty resins or coating additives | Applied in graft copolymerization or polymer modification |
Manufacturing Quality Control of 4-Chlorostyrene
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (p-Chlorostyrene Content) | Gas Chromatography (GC) with FID detector | Separation and quantification based on retention time and peak area relative to a certified reference standard. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a controlled anhydrous medium. |
| Acidity (as HCl) | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 430 nm | Comparison of sample color intensity against platinum-cobalt standard solutions or absorbance measurement at specified wavelength. |
| Residue on Evaporation | Gravimetric Analysis | Evaporation of a known sample mass under controlled conditions followed by weighing of non-volatile residue. |
| Chlorinated By-products (e.g., alpha,alpha-dichloro-p-xylene) | Gas Chromatography-Mass Spectrometry (GC-MS) | Separation by GC coupled with mass spectral identification and semi-quantitative analysis of chlorinated aromatic impurities. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals after acid digestion by measuring absorbance of ground-state atoms in flame or graphite furnace. |
| Non-Volatile Residue | Gravimetric Analysis | Same principle as Residue on Evaporation but performed per ASTM D129 specification for organic liquids. |
| Refractive Index | Refractometry | Measurement of light bending angle at air-sample interface using calibrated refractometer, correlated to purity and composition. |
| Density at 20 degC | Digital Density Meter or Pycnometer | Determination of mass per unit volume at standardized temperature using oscillating U-tube or calibrated glass pycnometer. |
| Peroxide Value | Iodometric Titration | Oxidation of iodide to iodine by peroxides, followed by titration of liberated iodine with standardized sodium thiosulfate. |
| Total Chlorine (organic + inorganic) | Oxygen Bomb Combustion followed by Ion Chromatography (IC) | High-temperature combustion converts all chlorine to chloride ions, which are then separated and quantified by IC conductivity detection. |
