Manufacturing Quality Control of 1,2-Bis(chloromethyl)benzene
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard using a calibrated column and carrier gas. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based solvent system; endpoint detected amperometrically. |
| Acidity (as HCl) | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution with phenolphthalein or potentiometric endpoint detection. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement | Comparison of sample color to platinum-cobalt standard solutions or measurement of absorbance at 455 nm in a 10 cm cell. |
| Density at 20 degC | Digital Density Meter | Measurement of oscillation frequency of a U-tube filled with sample, correlated to density via calibration with air and water. |
| Refractive Index at 20 degC | Refractometry | Determination of refractive index by measuring the critical angle of total internal reflection at the prism-sample interface. |
| Non-Volatile Residue | Gravimetric Analysis | Evaporation of a known mass of sample under controlled conditions followed by weighing of residual solids after drying to constant mass. |
| Chloride Ion (Cl-) | Ion Chromatography (IC) | Separation of anions on an ion-exchange column with conductivity detection; quantification via external calibration curve. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Atomization of acid-digested sample in flame or graphite furnace, followed by absorption measurement at characteristic wavelength for lead. |
| Residual Solvents | Gas Chromatography (GC) with Headspace Sampling | Headspace equilibration followed by GC separation and FID detection; quantified against solvent standards. |
| Aldehyde Impurities | UV-Vis Spectrophotometry after Derivatization | Reaction with 2,4-dinitrophenylhydrazine to form hydrazone derivatives, measured at ~450 nm. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution in a standardized cell at specified temperature and wavelength. |
