Manufacturing Quality Control of 1,2,3,4-Tetramethylbenzene
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies 1,2,3,4-tetramethylbenzene peak area relative to calibration standards using flame ionization detection. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration based on iodine consumption in a pyridine-methanol solvent system. |
| Acid Number | Acid-Base Titration with NaOH | Determines acidic impurities by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 455 nm | Evaluates yellowness by comparing sample color to APHA platinum-cobalt standards or measuring absorbance at 455 nm. |
| Density at 20 C | Digital Density Meter | Measures mass per unit volume using oscillating U-tube principle calibrated with air and water. |
| Refractive Index at 20 C | Abbe Refractometer | Determines ratio of light velocity in air versus sample using critical angle measurement of total internal reflection. |
| Non-Volatile Residue | Gravimetric Analysis after Evaporation | Quantifies residue by evaporating known sample mass under controlled conditions and weighing the residual solids. |
| Sulfur Content | Oxidative Combustion followed by Ion Chromatography (IC) | Converts organic sulfur to sulfate via high-temperature combustion, then quantifies sulfate anion by IC conductivity detection. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) after acid digestion | Measures total heavy metals after microwave-assisted nitric acid digestion, using graphite furnace AAS for trace-level detection. |
| Chlorinated Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and quantifies chlorinated aromatic impurities based on retention time and characteristic mass fragments. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Detects volatile organic solvents by analyzing equilibrium vapor phase above heated sample using GC-FID. |
| Total Volatile Impurities | Gas Chromatography (GC) with Internal Standard | Quantifies sum of volatile impurities by comparing peak areas to an added non-interfering internal standard. |
