Manufacturing Quality Control of 2,5-DIMETHYLTHIOPHENOL
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies main component peak area relative to calibration curve using internal or external standard. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric reaction between iodine and water in pyridine/methanol medium. |
| Acidity (as H2SO4) | Acid-Base Titration with NaOH | Neutralizes acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement | Compares sample color to APHA platinum-cobalt standard scale using spectrophotometer at 455 nm. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after controlled high-temperature ashing and weighing. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals by atomizing sample in flame/graphite furnace and measuring absorbance at characteristic wavelength. |
| Sulfur Content | Combustion IC (Ion Chromatography) | Oxidizes sulfur to sulfate, then separates and quantifies sulfate ions using conductivity detection. |
| Chloride Content | Potentiometric Titration with AgNO3 | Titrates chloride ions with silver nitrate using silver indicator electrode and reference electrode. |
| Non-Volatile Matter | Gravimetric Analysis | Determines residue after evaporation of specified sample mass under controlled temperature and vacuum. |
| Odor | Sensory Evaluation | Qualified personnel assess odor intensity and character against reference standards per ASTM E544. |
| Density at 20 degC | Digital Density Meter | Measures oscillation frequency of U-tube filled with sample to calculate density based on calibration. |
| Refractive Index at 20 degC | Refractometry | Determines refractive index by measuring angle of light refraction at air-sample interface using calibrated refractometer. |
