Manufacturing Quality Control of 1,2,3,4,5-Pentamethylcyclopentadiene
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies main component peak area relative to calibration standard using retention time matching and response factor correction. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between iodine, sulfur dioxide, and water in anhydrous methanol-based solvent. |
| Residue on Evaporation | Gravimetric Analysis | Determines non-volatile residue mass after controlled evaporation of a defined sample volume under specified temperature and vacuum conditions. |
| Acidity (as HCl) | Acid-Base Titration with NaOH | Neutralizes acidic impurities using standardized sodium hydroxide solution with phenolphthalein endpoint detection. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 430 nm | Compares sample color intensity against platinum-cobalt standard solutions or measures absorbance at 430 nm in 1 cm cell. |
| Density at 20 degC | Digital Density Meter | Determines mass per unit volume using oscillating U-tube principle with temperature-controlled measurement. |
| Refractive Index at 20 degC | Abbe Refractometer | Measures bending of light passing through sample at specified wavelength (589 nm) and temperature to determine refractive index. |
| Non-Volatile Matter | Gravimetric Analysis | Weighs residue after drying sample film under nitrogen flow at 105 degC for fixed duration. |
| Heavy Metals (as Pb) | ICP-OES | Quantifies total heavy metal content by plasma excitation and elemental emission line intensity measurement. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Peroxide Value | Iodometric Titration | Measures peroxides via oxidation of iodide to iodine under acidic conditions, followed by titration with standardized sodium thiosulfate. |
| Boiling Range | Gas Chromatography (GC) or Distillation Apparatus | Determines temperature interval over which 5% to 95% of sample distills under controlled atmospheric pressure and heating rate. |
