Manufacturing Quality Control of cis-1,4-Dichloro-2-butene
| 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 optimized chromatographic conditions. |
| cis-1,4-Dichloro-2-butene Isomer Content | Gas Chromatography (GC) with capillary column | Separation and quantification of cis-isomer relative to trans-isomer and other structural isomers using retention time and response factors. |
| Trans-1,4-Dichloro-2-butene Content | Gas Chromatography (GC) | Specific quantification of trans-isomer as impurity using calibrated GC-FID or GC-MS. |
| Residual Solvents (e.g., hexane, methanol) | Gas Chromatography (GC) with headspace sampling | Volatile organic impurities are vaporized in sealed vials and quantified by headspace-GC-FID against external standards. |
| Water Content | Karl Fischer Titration (coulometric mode) | Electrochemical titration where iodine generated coulometrically reacts stoichiometrically with water in the sample. |
| Acidity (as HCl) | Acid-Base Titration with NaOH and potentiometric endpoint | Free HCl or acidic impurities are neutralized with standardized sodium hydroxide; endpoint detected by pH change. |
| Non-Volatile Residue | Gravimetric Analysis (Evaporation and Weighing) | Sample is evaporated to dryness under controlled temperature and pressure; residue mass is determined by weight difference. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 455 nm | Color intensity is assessed by matching to APHA platinum-cobalt standard solutions or measuring absorbance at specified wavelength. |
| Density at 20 degC | Digital Density Meter (Oscillating U-tube principle) | Density is calculated from the oscillation period of a U-shaped tube filled with sample at controlled temperature. |
| Refractive Index at 20 degC | Digital Refractometer | Refractive index is determined by measuring the critical angle of total internal reflection of light through the liquid sample. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) after wet digestion | Sample is digested with nitric acid, then lead concentration is measured by AAS at characteristic absorption wavelength. |
| Chloride Ion (inorganic) | Ion Chromatography (IC) with conductivity detection | Inorganic chloride is separated on anion-exchange column and quantified by conductivity response relative to calibration standards. |
