Manufacturing Quality Control of TRI(ETHYLENE GLYCOL) DI-P-TOLUENESULFONATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component by retention time and peak area against calibrated standard. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between iodine, sulfur dioxide, and water in anhydrous methanol. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH | Neutralizes acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 430 nm | Compares sample color to APHA platinum-cobalt standards or measures absorbance at 430 nm. |
| Density at 20 degC | Digital Density Meter | Determines mass per unit volume using oscillating U-tube principle. |
| Refractive Index at 20 degC | Refractometry | Measures bending of light through sample to infer purity and composition. |
| Residue on Evaporation | Gravimetric Analysis | Weighs non-volatile residue after controlled evaporation under specified conditions. |
| Chloride Content | Ion Chromatography (IC) or Potentiometric Titration with AgNO3 | Separates and quantifies chloride ions via conductivity detection or silver nitrate titration endpoint. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) or ICP-OES | Atomizes sample and measures absorption/emission of characteristic wavelengths for metal elements. |
| Aldehydes (as Acetaldehyde) | Spectrophotometry after Derivatization with DNPH | Forms colored hydrazone derivative with 2,4-dinitrophenylhydrazine, measured at ~450 nm. |
| Viscosity at 25 degC | Capillary Viscometry | Determines kinematic viscosity by measuring flow time through calibrated capillary tube under gravity. |
| Non-Volatile Residue | Gravimetric Analysis | Measures weight of residue remaining after heating sample to 105 degC until constant mass. |
