Manufacturing Quality Control of 1,2-Bis(bromomethyl)benzene
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantitative determination based on peak area comparison against a certified reference standard using a non-polar capillary column. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based solvent system. |
| Acidity (as HBr) | Acid-Base Titration with NaOH | Neutralization of acidic impurities (e.g., HBr) using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis | Heating sample to 700-800 C in a platinum crucible, then weighing the non-volatile inorganic residue after cooling. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals by atomizing the acid-digested sample and measuring absorbance at characteristic wavelengths. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and quantification of chloride ions using an anion-exchange column and conductivity detection. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Measurement of yellowness intensity by comparing sample color to APHA platinum-cobalt standard solutions at 455 nm. |
| Density at 20 C | Digital Density Meter | Determination of mass per unit volume using oscillating U-tube principle calibrated with air and water. |
| Refractive Index at 20 C | Refractometry | Measurement of light bending angle as it passes through the liquid sample using a calibrated Abbe refractometer. |
| Boiling Point Range | Distillation Apparatus (ASTM D1078) | Determination of temperature interval over which 90% of the sample distills under reduced pressure (e.g., 10 mmHg). |
| Non-Volatile Residue | Evaporation Gravimetry | Evaporation of a fixed sample mass on a pre-weighed dish at 105 C, followed by weighing the residual residue. |
| Organic Volatile Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Separation and identification of trace volatile organics via retention time and mass spectral matching against libraries. |
