Manufacturing Quality Control of CIS-1,2-DICHLOROETHYLENE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Separation and quantification based on retention time and peak area against a certified reference standard. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based reagent. |
| Acidity (as HCl) | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Non-Volatile Residue | Gravimetric Analysis | Evaporation of a known sample mass under controlled conditions followed by weighing of residual solids. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Measurement of yellowness intensity by comparison to APHA color standards or absorbance at 430 nm. |
| Density at 20 degC | Digital Density Meter | Determination of mass per unit volume using oscillating U-tube principle calibrated with water and air. |
| Refractive Index at 20 degC | Refractometry | Measurement of light bending angle through the sample at specified wavelength (e.g., sodium D line) to infer purity. |
| Chlorinated Impurities (e.g., 1,1-DCE, trans-1,2-DCE) | Gas Chromatography (GC) with ECD or MS detection | Separation and selective detection of structurally related chlorinated isomers using retention time and response factors. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of metal content after wet digestion and atomization in a graphite furnace or flame. |
| Residual Solvents (e.g., acetone, methanol) | Headspace Gas Chromatography (HS-GC) | Thermal equilibration of sample in sealed vial followed by GC analysis of volatile organic compounds in headspace gas. |
| Total Chloride (organic + inorganic) | Oxygen Flask Combustion followed by Potentiometric Titration | Combustion of sample to convert all chlorine to chloride ion, then titration with silver nitrate using silver electrode detection. |
| Odor Threshold (Qualitative) | Sensory Evaluation | Trained personnel assess presence/absence of characteristic chlorinated odor at defined dilution levels. |
