Manufacturing Quality Control of 1,2-DIIODOETHANE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (1,2-Diiodoethane content) | Gas Chromatography (GC) with FID detector | Quantitative separation and detection based on volatility and retention time relative to a certified reference standard. |
| Iodine Content | Iodometric Titration | Oxidation of iodide to iodine by excess potassium iodate in acidic medium, followed by back-titration with sodium thiosulfate. |
| Acidity (as HI) | Acid-Base Titration with NaOH | Neutralization of acidic impurities (e.g., hydroiodic acid) using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Water Content | Karl Fischer Coulometric Titration | Electrochemical generation of iodine to react stoichiometrically with water; quantification via charge measurement. |
| Residue on Evaporation | Gravimetric Analysis | Evaporation of a known sample mass under controlled conditions followed by weighing of non-volatile residue. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 430 nm | Comparison of sample color intensity against APHA platinum-cobalt standards or absorbance measurement at specified wavelength. |
| Density at 20 degC | Digital Density Meter | Measurement of mass per unit volume using oscillating U-tube principle calibrated with water and air. |
| Refractive Index at 20 degC | Abbe Refractometer | Determination of refractive index based on critical angle of total internal reflection at the sample-prism interface. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of metal impurities after acid digestion and chelation, using element-specific hollow cathode lamp absorption. |
| Non-Volatile Residue | Gravimetric Analysis | Evaporation of sample under vacuum at elevated temperature followed by precise weighing of residual solids. |
| Chloride Impurity | Ion Chromatography (IC) with Conductivity Detection | Separation of anions on ion-exchange column and quantitative detection based on electrical conductivity of eluent. |
| Peroxide Value | Cerium(IV) Sulfate Titration | Oxidation of iodide to iodine by peroxides present, followed by titration of liberated iodine with standardized ceric sulfate. |
