Manufacturing Quality Control of 4-(Ethoxyethoxy)styrene
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (P-(1-Ethoxyethoxy)styrene content) | GC-FID | Quantitative determination using flame ionization detection with internal or external standard calibration. |
| Related Substances (impurities) | GC-MS | Identification and quantification of organic impurities based on mass spectral fragmentation patterns and retention times. |
| Residual Solvents (e.g., ethanol, THF) | GC-FID | Separation and quantification of volatile solvents using capillary column and FID detection. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration based on iodine consumption in a reaction with water. |
| Acidity (as acetic acid) | Acid-Base Titration | Neutralization of acidic impurities with standardized NaOH solution using phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Measurement of yellowness index by comparison to platinum-cobalt standards or absorbance at 455 nm. |
| Density at 20 degC | Digital Density Meter | Determination via oscillating U-tube principle calibrated with air and water standards. |
| Refractive Index at 20 degC | Abbemat Refractometer | Measurement of light bending angle at specified wavelength (589 nm) using total internal reflection. |
| Peroxide Value | Iodometric Titration | Oxidation of iodide to iodine by peroxides, followed by titration with standardized sodium thiosulfate. |
| Non-Volatile Residue | Gravimetric Analysis | Evaporation of sample under controlled conditions followed by weighing of residual solids. |
| Chloride Content | Ion Chromatography (IC) | Separation of chloride anions on anion-exchange column with conductivity detection. |
| Heavy Metals (as Pb) | ICP-OES | Elemental quantification after acid digestion using plasma excitation and optical emission spectroscopy. |
