Manufacturing Quality Control of sec-Butyl disulfide
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantitative separation and detection of DBDS and impurities based on volatility and retention time. |
| Water Content | Karl Fischer Titration | Electrometric titration measuring water via iodine-sulfur dioxide reaction in anhydrous methanol medium. |
| Acidity (as H2SO4) | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement | Comparison of sample color against platinum-cobalt standard solutions at 455 nm wavelength. |
| Density at 20 C | Pycnometry or Digital Density Meter | Measurement of mass per unit volume using calibrated glass pycnometer or oscillating U-tube principle. |
| Refractive Index at 20 C | Refractometry | Determination of light bending angle through liquid sample using calibrated refractometer at specified temperature. |
| Non-Volatile Residue | Gravimetric Analysis (Evaporation) | Evaporation of known sample mass at 105 C followed by weighing of residual solids. |
| Sulfur Content | Combustion IC (Ion Chromatography) after oxidation | Oxidation of organic sulfur to sulfate, followed by anion exchange separation and conductivity detection. |
| Heavy Metals (as Pb) | Flame Atomic Absorption Spectroscopy (FAAS) | Atomization of sample in air-acetylene flame and quantification of metal absorption at characteristic wavelength. |
| Residual Solvents (e.g., hexane, ethanol) | Gas Chromatography (GC) with FID or TCD | Separation and detection of volatile solvents based on polarity and boiling point differences. |
| Peroxide Value | Iodometric Titration | Liberation of iodine from potassium iodide by peroxides, followed by titration with sodium thiosulfate. |
| Odor Threshold (Qualitative) | Sensory Evaluation by Trained Panel | Organoleptic assessment against reference standards to detect off-odor intensity and character. |
