Manufacturing Quality Control of Pentamethylbenzene
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies pentamethylbenzene peak area relative to calibration standards using retention time and response factor. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Residue on Evaporation | Gravimetric Analysis | Determines non-volatile residue by evaporating a known sample mass under controlled temperature and weighing the residue. |
| Acidity (as H2SO4) | Acid-Base Titration with NaOH | Neutralizes acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride ions based on ion exchange retention and conductivity detection. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Measures absorbance of ground-state metal atoms at characteristic wavelengths after acid digestion. |
| Non-Volatile Matter | Gravimetric Analysis | Weighs residue remaining after evaporation of sample under nitrogen stream at 105 C. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Compares sample color intensity against platinum-cobalt standard solutions at 455 nm. |
| Density at 20 C | Digital Density Meter | Determines mass per unit volume using oscillating U-tube principle with temperature control. |
| Refractive Index at 20 C | Refractometry | Measures bending of light passing through sample at specified wavelength (589 nm) and temperature. |
| Boiling Range | Gas Chromatography (GC) or Distillation | Identifies temperature interval over which 5% to 95% of sample distills under controlled conditions. |
| Organic Impurities (Related Substances) | Gas Chromatography-Mass Spectrometry (GC-MS) | Separates volatile components and identifies/quantifies impurities via mass spectral fragmentation patterns. |
