Manufacturing Quality Control of Dimethyl terephthalate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) | Quantifies DMT content by separation and flame ionization detection relative to internal/external standard. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Measures yellowness index by comparing sample absorbance at 430 nm to platinum-cobalt standards. |
| Moisture Content | Karl Fischer Titration | Determines water via coulometric or volumetric titration with iodine generated electrochemically or added stoichiometrically. |
| Acid Value | Acid-Base Titration | Measures free carboxylic acid impurities by titration with standardized KOH in alcoholic medium using phenolphthalein. |
| Ash Content | Gravimetric Analysis | Determines inorganic residue after controlled high-temperature combustion and weighing of the residual ash. |
| Iron Content | ICP-OES | Quantifies trace iron by measuring atomic emission intensity at characteristic wavelength after acid digestion. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Detects lead and other heavy metals via absorption of specific wavelength light by ground-state atoms in flame or graphite furnace. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile impurities as weight remaining after heating at specified temperature in muffle furnace. |
| Melting Point | Capillary Melting Point Apparatus | Determines purity indicator by observing temperature range at which solid transitions to liquid under controlled heating. |
| Volatile Matter | Thermogravimetric Analysis (TGA) | Quantifies weight loss upon heating under inert atmosphere, indicating low-boiling impurities and solvents. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride ions based on anion exchange retention and conductivity detection. |
| Sulfated Ash | Gravimetric Analysis | Measures total inorganic sulfate content after sulfuric acid treatment and high-temperature ignition to constant weight. |
