Manufacturing Quality Control of P,P'-DIOCTYLDIPHENYLAMINE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative separation and detection of target compound based on retention time and peak area against calibrated standards. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Volatile impurities are vaporized in sealed vials and quantified by GC after equilibrium partitioning into headspace. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based reagent. |
| Acid Value | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution with phenolphthalein endpoint detection. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 455 nm | Comparison of sample color intensity to APHA platinum-cobalt standard scale using transmitted light at specified wavelength. |
| Specific Gravity | Digital Density Meter | Measurement of mass per unit volume at controlled temperature using oscillating U-tube principle. |
| Refractive Index | Refractometry | Determination of light bending angle at air-sample interface using calibrated prism instrument at 20 C. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of metal impurities after acid digestion by measuring absorption of element-specific hollow cathode lamp radiation. |
| Non-Volatile Residue | Gravimetric Analysis (Weight Loss on Drying) | Evaporation of volatile components followed by weighing of residual solids after drying at 105 C. |
| Peroxide Value | Iodometric Titration | Oxidation of potassium iodide by peroxides to liberate iodine, titrated with standardized sodium thiosulfate. |
| Residual N-Phenylaniline | Gas Chromatography-Mass Spectrometry (GC-MS) | Selective identification and quantification of unreacted starting material using retention time and characteristic ion fragments. |
| Residual 2,4,4-Trimethylpentene | Gas Chromatography (GC) with FID detection | Quantitative determination of unreacted alkene by GC separation and flame ionization detection relative to calibration curve. |
