Manufacturing Quality Control of 1,3-Dibromobenzene
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies 1,3-dibromobenzene peak area relative to a calibration curve using an internal or external standard. |
| Related Substances | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and semi-quantifies impurities (e.g., isomers, bromination by-products) based on retention time and mass spectral matching. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration using iodine generated in situ; reaction stoichiometry is 1:1 with water. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic residue after controlled high-temperature ashing and weighing. |
| Acidity (as HBr) | Acid-Base Titration with NaOH | Neutralizes acidic impurities (e.g., residual HBr) using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement | Compares sample color to APHA platinum-cobalt standard solutions at 455 nm using a calibrated colorimeter. |
| Density at 20 C | Digital Density Meter | Measures mass per unit volume using oscillating U-tube principle calibrated with air and water standards. |
| Refractive Index at 20 C | Refractometry | Determines refractive index by measuring angle of light refraction at the liquid-air interface using a calibrated Abbe refractometer. |
| Boiling Range | Distillation (ASTM D1078) | Determines temperature interval over which 90% of sample distills under controlled atmospheric pressure and heating rate. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Measures total heavy metal content after wet digestion by quantifying absorbance of ground-state atoms in flame or graphite furnace. |
| Non-Volatile Residue | Evaporation and Gravimetry | Determines residue remaining after evaporation of a fixed sample volume under controlled temperature and vacuum, followed by weighing. |
