Manufacturing Quality Control of 2-Chlorostyrene
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (2-Chlorostyrene Content) | Gas Chromatography (GC) with FID detection | Quantitative separation and detection based on retention time and peak area using a calibrated standard. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a controlled anhydrous environment. |
| 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 standards or absorbance measurement at specified wavelength. |
| Density at 20 degC | Digital Density Meter (Oscillating U-tube) | Measurement of sample density via resonant frequency shift of a vibrating U-shaped tube filled with the liquid. |
| Refractive Index at 20 degC | Abbe Refractometer | Determination of refractive index by measuring the critical angle of total internal reflection at the prism-sample interface. |
| Residue on Evaporation | Gravimetric Analysis | Evaporation of a known volume under controlled conditions followed by weighing of non-volatile residue. |
| Chloride Ion (inorganic) | Ion Chromatography (IC) with conductivity detection | Separation of anions on an ion-exchange column and quantitative detection via electrical conductivity. |
| Heavy Metals (Pb, Cd, Hg, Cr) | ICP-OES | Atomization and excitation of metals in high-temperature plasma; detection via element-specific emission wavelengths. |
| Peroxide Value | Iodometric Titration | Oxidation of iodide to iodine by peroxides, followed by titration of liberated iodine with standardized sodium thiosulfate. |
| Non-Volatile Residue | Gravimetric Analysis after Solvent Evaporation | Evaporation of sample in a tared dish, drying at 105 degC, and weighing of residual solids. |
| Odor Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Separation by GC followed by identification and semi-quantification of volatile odorants via mass spectral fragmentation patterns. |
