Manufacturing Quality Control of 4-ETHYLTOLUENE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (p-Ethyltoluene Content) | Gas Chromatography (GC) with FID detection | Quantitative separation and detection based on volatility and retention time relative to certified reference standard. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based reagent. |
| Acid Number | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 455 nm | Comparison of sample color intensity against platinum-cobalt standard solutions or absorbance measurement at specified wavelength. |
| Density at 20 degC | Digital Density Meter or Pycnometer | Measurement of mass per unit volume using oscillating U-tube principle or calibrated glass flask. |
| Refractive Index at 20 degC | Refractometry | Determination of light bending angle at air-sample interface using calibrated Abbe refractometer. |
| Non-Volatile Residue | Gravimetric Analysis after Evaporation | Evaporation of known sample mass under controlled conditions followed by weighing of residual solids. |
| Sulfur Content | Oxidative Combustion followed by Ion Chromatography (IC) or UV Fluorescence | Complete combustion to SO2, followed by quantitative detection via conductivity or fluorescence emission. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) after acid digestion | Acid decomposition of organic matrix followed by atomization and absorption measurement at element-specific wavelength. |
| Residual Solvents (e.g., benzene, toluene) | Gas Chromatography with Headspace Sampling (HS-GC) | Equilibration of volatile components in headspace, followed by GC separation and FID detection. |
| Peroxide Value | Iodometric Titration | Oxidation of potassium iodide by peroxides to liberate iodine, titrated with standardized sodium thiosulfate. |
| Chlorinated Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Separation by GC followed by electron ionization and mass-selective detection of chlorinated species. |
