Manufacturing Quality Control of N-VINYLPHTHALIMIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | GC-FID | Quantification by gas chromatography with flame ionization detection using an internal standard and calibration curve. |
| Water Content | Karl Fischer Titration | Coulometric or volumetric titration based on the reaction of iodine with water in a pyridine-methanol solvent system. |
| Residual Solvents | GC-FID | Separation and quantification of volatile organic impurities using headspace or direct injection GC. |
| Acid Value | Acid-Base Titration | Neutralization of acidic impurities with standardized KOH solution in alcoholic medium, detected by potentiometric endpoint. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Measurement of yellowness index against platinum-cobalt standards using spectrophotometric absorbance at 455 nm. |
| Density | Digital Density Meter | Determination via oscillating U-tube principle measuring frequency shift correlated to sample density. |
| Refractive Index | Refractometry | Measurement of light bending angle at air-sample interface using calibrated Abbe refractometer or digital equivalent. |
| Peroxide Value | Iodometric Titration | Oxidation of iodide to iodine by peroxides in acetic acid-chloroform, followed by titration with standardized sodium thiosulfate. |
| Heavy Metals (as Pb) | AAS | Atomic absorption spectroscopy after wet digestion and matrix matching, measuring absorbance at element-specific wavelength. |
| Non-Volatile Residue | Gravimetric Analysis | Evaporation of sample under controlled conditions followed by weighing of residue after drying to constant mass. |
| UV Absorbance (at 280 nm) | UV-Vis Spectrophotometry | Measurement of absorbance in methanol or ethanol solution to detect conjugated impurities or degradation products. |
| Gas Impurities (O2, N2, CO2) | GC-TCD | Separation on molecular sieve column and thermal conductivity detection for permanent gases in headspace vapor. |
