Manufacturing Quality Control of 4-Chloro-alpha-methylstyrene
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (p-Chloromethylstyrene content) | Gas Chromatography (GC) | Quantitative separation and detection using a capillary column with flame ionization detection. |
| Water Content | Karl Fischer Titration | Electrochemical titration based on the reaction of iodine with water in a methanol-based reagent. |
| Chlorine Content | Oxygen Flask Combustion followed by Potentiometric Titration | Combustion releases chlorine as chloride, which is titrated with silver nitrate using a silver electrode. |
| 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. |
| Density at 20 C | Digital Density Meter | Measurement of mass per unit volume using oscillating U-tube principle. |
| Refractive Index at 20 C | Refractometry | Determination of light bending angle at air-sample interface using calibrated prism instrument. |
| Residue on Evaporation | Gravimetric Analysis | Evaporation of known sample mass under controlled conditions followed by weighing of non-volatile residue. |
| Peroxide Value | Iodometric Titration | Oxidation of iodide to iodine by peroxides, followed by titration with standardized sodium thiosulfate. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Atomization of sample and quantification of metal absorption at characteristic wavelengths. |
| Total Volatile Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Separation and identification of volatile organic impurities via retention time and mass fragmentation patterns. |
| Stability (Thermal Decomposition Onset) | Differential Scanning Calorimetry (DSC) | Measurement of heat flow difference during controlled heating to detect exothermic decomposition events. |
