Manufacturing Quality Control of 1-Ethyl-3,5-difluorobenzene
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantitative determination based on peak area comparison against certified reference standard under validated chromatographic conditions. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Volatile impurities are equilibrated in headspace vial and quantified by GC-FID using external calibration. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration where iodine generated coulometrically reacts stoichiometrically with water in the sample. |
| Acidity (as HCl) | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution with phenolphthalein endpoint detection. |
| Non-Volatile Residue | Gravimetric Analysis (Evaporation and Weighing) | Sample is evaporated to dryness under controlled temperature, and residue mass is determined by weight difference. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification after acid digestion, based on characteristic atomic emission intensities at specific wavelengths. |
| Chlorinated Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Identification and quantification of chlorinated by-products via retention time and characteristic mass fragment patterns. |
| Refractive Index | Refractometry | Measurement of light refraction angle through liquid sample at specified temperature to assess compositional purity. |
| Specific Gravity | Digital Density Meter | Determination of density relative to water using oscillating U-tube principle for batch consistency verification. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement | Evaluation of yellowness intensity against platinum-cobalt standards using spectrophotometer at 430 nm. |
| Distillation Range | Simple Distillation with Thermometer | Temperature range over which 10% to 90% of sample volume distills under controlled atmospheric pressure. |
| Residual Catalyst (Pd) | ICP-MS | Ultra-trace quantification of palladium after microwave-assisted acid digestion using isotopic mass detection. |
