Manufacturing Quality Control of 1,2-divinylbenzene
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (1,2-Divinylbenzene content) | Gas Chromatography (GC) with FID detection | Separation and quantification based on retention time and peak area relative to calibrated standards. |
| Purity by GC | Gas Chromatography (GC) with FID or MS detection | Quantitative determination of main component and impurities using internal or external standard calibration. |
| Water content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based solvent system. |
| Acidity (as H2SO4) | 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. |
| Density at 20 C | Digital Density Meter or Pycnometer | Measurement of mass per unit volume using oscillating U-tube principle or calibrated glass pycnometer. |
| Refractive Index at 20 C | Refractometry | Determination of light bending angle at air-sample interface using calibrated Abbe refractometer. |
| Vinyl Content (by bromination) | Bromination followed by Potentiometric Titration | Addition of bromine to vinyl groups, then back-titration of excess bromine with thiosulfate. |
| Peroxide Value | Iodometric Titration | Oxidation of iodide to iodine by organic peroxides, followed by titration of liberated iodine with sodium thiosulfate. |
| Residue on Evaporation | Gravimetric Analysis | Evaporation of known sample mass under controlled conditions and weighing of non-volatile residue. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of metal ions after acid digestion and atomization in flame or graphite furnace. |
| Total Chloride Content | Ion Chromatography (IC) or Potentiometric Titration with AgNO3 | Separation and detection of chloride anions via conductivity or direct titration with silver nitrate. |
