Manufacturing Quality Control of DIETHYL VINYLPHOSPHONATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component peak area relative to calibration curve using volatile organic compound separation and flame ionization detection. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between iodine, sulfur dioxide, and water in a methanol-based electrolyte. |
| Acidity (as H3PO4) | Acid-Base Titration with NaOH | Neutralizes acidic impurities using standardized sodium hydroxide solution and phenolphthalein or potentiometric endpoint detection. |
| Color | APHA Color Scale (Visual or Spectrophotometric) | Compares sample color to platinum-cobalt standard solutions or measures absorbance at 455 nm against distilled water blank. |
| Density at 20 C | Digital Density Meter (Oscillating U-tube) | Determines mass per unit volume from resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Refractive Index at 20 C | Refractometry | Measures bending of light through sample at specified temperature to infer purity and composition based on Snell's law. |
| Residue on Evaporation | Gravimetric Analysis | Weighs non-volatile residue after controlled evaporation of a known sample mass under specified temperature and vacuum conditions. |
| Chloride Content | Ion Chromatography (IC) or Potentiometric Titration | Separates and quantifies chloride ions via conductivity detection (IC) or silver nitrate titration with silver electrode endpoint (potentiometry). |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES | Atomizes and excites sample in argon plasma; quantifies metals by measuring element-specific emission wavelengths. |
| Phosphate Impurities (e.g., diethyl phosphoric acid) | HPLC with UV Detection | Separates polar phosphoric acid derivatives on reversed-phase or ion-pair column and detects via UV absorbance at 190-210 nm. |
| Distillation Range | Micro Distillation Apparatus (ASTM D1078) | Measures initial boiling point and final boiling point under controlled heating rate and pressure to assess volatility distribution. |
| Specific Odor (Organoleptic) | Sensory Evaluation | Trained personnel assess presence/absence of off-odor inconsistent with typical ethyl vinyl phosphonate profile under controlled conditions. |
