Manufacturing Quality Control of 2-Chloronaphthalene
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (2-Chloronaphthalene Content) | Gas Chromatography (GC) with FID detector | Quantitative determination based on retention time and peak area comparison against certified reference standard. |
| Water Content | Karl Fischer Titration | Electrochemical titration measuring water via iodine-sulfur dioxide reaction in methanol-based solvent. |
| 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 455 nm | Evaluation of yellowish discoloration by matching sample absorbance to APHA color scale standards. |
| Residue on Ignition | Gravimetric Analysis | Weighing non-volatile residue remaining after controlled high-temperature ashing of a weighed sample. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals after acid digestion, based on absorption of characteristic atomic spectral lines. |
| Non-Volatile Residue | Gravimetric Evaporation | Weighing residue left after evaporation of a fixed sample volume under controlled temperature and airflow. |
| Chloride Ion (as Cl-) | Potentiometric Titration with AgNO3 | Titration using silver nitrate and silver/silver chloride electrode to detect endpoint via potential change. |
| Refractive Index | Refractometry | Measurement of light bending angle at air-sample interface at specified temperature (e.g., 20 C) using calibrated refractometer. |
| Density | Pycnometry or Digital Density Meter | Determination of mass per unit volume at standard temperature (e.g., 20 C) using calibrated glass pycnometer or oscillating U-tube principle. |
| Boiling Range | Distillation (ASTM D1078) | Fractional distillation under reduced pressure to determine initial and final boiling points of the main component. |
| Organic Impurities (Related Substances) | Gas Chromatography-Mass Spectrometry (GC-MS) | Separation and identification of structurally related compounds (e.g., naphthalene, 1-chloronaphthalene) using retention time and mass spectra matching. |
