Manufacturing Quality Control of P-TOLUENESULFONIC ACID N-BUTYL ESTER
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component peak area relative to calibrated standard using flame ionization detection. |
| 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 acid content by titrating with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Color | APHA Color Scale (Visual or Spectrophotometric) | Compares sample color to platinum-cobalt standard solutions or measures absorbance at 455 nm. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing and weighing. |
| Heavy Metals | ICP-OES | Quantifies trace metal impurities (e.g., Pb, Cd, As) by plasma excitation and elemental emission spectroscopy. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Sulfate Content | Barium Sulfate Gravimetry | Precipitates sulfate as BaSO4 and determines mass after filtration and drying. |
| Refractive Index | Refractometry | Measures bending of light through liquid sample at specified temperature to assess purity and concentration. |
| Specific Gravity | Pycnometry | Determines density ratio relative to water using calibrated glass pycnometer at controlled temperature. |
| Volatility Residue | Thermogravimetric Analysis (TGA) | Measures weight loss under controlled heating to assess volatile impurities and thermal stability. |
| Organic Impurities (Related Substances) | HPLC with UV Detection | Separates and quantifies structurally related compounds using reversed-phase column and UV absorbance detection. |
