Manufacturing Quality Control of 4-Vinylanilin
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID | Quantifies 4-vinylaniline peak area relative to calibration curve using flame ionization detection. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric reaction between water and iodine in pyridine-methanol medium. |
| Color | APHA Color Scale (Visual or Spectrophotometric) | Compares sample color to platinum-cobalt standard solutions using visual assessment or UV-Vis absorbance at 455 nm. |
| Acid Value | Acid-Base Titration (NaOH, phenolphthalein) | Determines free acidic impurities by titration with standardized sodium hydroxide solution. |
| Amine Value | Acid-Base Titration (HCl, methyl red) | Measures total primary amine content by back-titration after acylation or direct titration with HCl. |
| Residue on Ignition | Gravimetric Analysis | Weighs non-volatile residue remaining after high-temperature ashing in a muffle furnace. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals after acid digestion by measuring atomic absorption at characteristic wavelengths. |
| Chloride Content | Potentiometric Titration (AgNO3) | Detects chloride ions via silver nitrate titration monitored by silver electrode potential change. |
| Specific Gravity | Digital Density Meter | Measures mass per unit volume at specified temperature using oscillating U-tube principle. |
| Refractive Index | Refractometry | Determines ratio of light velocity in air vs. sample using critical angle measurement at 20 C. |
| Volatile Impurities | Headspace Gas Chromatography (HS-GC) | Identifies and quantifies low-boiling contaminants by GC analysis of vapor phase above heated sample. |
| Appearance | Visual Inspection | Assesses physical state, clarity, and presence of suspended particles or phase separation under controlled lighting. |
