Manufacturing Quality Control of TRIETHYL 2-PHOSPHONOBUTYRATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component peak area against calibrated standard; uses internal or external standard for calculation. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration with iodine-based reagent reacting stoichiometrically with water. |
| Acid Value | Acid-Base Titration with NaOH | Determines free carboxylic acid 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 standards or measures absorbance at 430 nm in a 10-mm cell. |
| Density at 20 C | Digital Density Meter (Oscillating U-tube) | Measures sample density based on resonant frequency shift of a vibrating U-shaped tube filled with the liquid. |
| Refractive Index at 20 C | Abbe Refractometer | Determines refractive index by measuring critical angle of total internal reflection of light at the sample-prism interface. |
| Residue on Evaporation | Gravimetric Analysis (Weight Loss on Drying) | Evaporates solvent under controlled conditions and weighs non-volatile residue after drying to constant mass. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies trace heavy metals by measuring absorption of specific wavelength light by ground-state metal atoms in flame or graphite furnace. |
| Residual Solvents (e.g., Hexane, Ethanol) | Headspace Gas Chromatography (HS-GC) | Extracts volatile solvents from sample matrix into headspace gas, then separates and quantifies via GC-FID. |
| Peroxide Value | Iodometric Titration | Measures peroxides by their oxidation of iodide to iodine under acidic conditions, followed by titration with sodium thiosulfate. |
| Chloride Content | Ion Chromatography (IC) or Potentiometric Titration | Separates and quantifies chloride ions using ion-exchange column and conductivity detection, or via silver nitrate titration with chloride-selective electrode. |
| Non-Volatile Matter | Gravimetric Analysis (Evaporation and Weighing) | Evaporates known mass of sample at specified temperature, dries residue, and determines mass of non-volatile residue. |
