Manufacturing Quality Control of 2-Vinylnaphthalene
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies 2-vinylnaphthalene peak area relative to calibration standards using flame ionization detection. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration with iodine-based reagent reacting stoichiometrically with water. |
| Acid Number | Acid-Base Titration with NaOH | Determines acidic impurities by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 430 nm | Compares sample color to APHA platinum-cobalt standard scale or measures absorbance at 430 nm in a 10 cm cell. |
| Residue on Evaporation | Gravimetric Analysis | Measures non-volatile residue after controlled evaporation of a weighed sample under specified temperature and vacuum conditions. |
| Density at 20 degC | Digital Density Meter (Oscillating U-tube) | Determines density based on resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Refractive Index at 20 degC | Refractometry | Measures refractive index using critical angle principle with sodium D-line (589 nm) light source. |
| Non-Volatile Matter | Gravimetric Analysis | Quantifies residue after evaporation of solvent and sample under defined heating conditions, expressed as mass percent. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Detects total heavy metals after wet digestion by measuring absorbance of atomic vapor at characteristic wavelengths. |
| Peroxide Value | Iodometric Titration | Measures peroxides via oxidation of iodide to iodine, followed by titration of liberated iodine with sodium thiosulfate. |
| Distillation Range | Vacuum Distillation Apparatus | Determines initial boiling point, final boiling point, and percentage distilled at specified temperatures under controlled vacuum. |
| Appearance | Visual Inspection | Assesses clarity and presence of suspended particles or phase separation against a white background under controlled lighting. |
