Manufacturing Quality Control of 4,4'-Methylenebis(2,6-di-tert-butylphenol)
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 280 nm, based on peak area comparison against a certified reference standard. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measured by observing the temperature range over which solid transforms to liquid in a capillary tube under controlled heating. |
| Appearance | Visual Inspection | Assessment of physical state and color by observation against standard white background under controlled lighting conditions. |
| Moisture Content | Karl Fischer Titration | Volumetric or coulometric titration measuring water content via stoichiometric reaction between iodine and water in pyridine/methanol medium. |
| Ash Content | Gravimetric Analysis (Incineration) | Residue mass after high-temperature incineration (550-600 C) followed by cooling and weighing; reflects inorganic impurities. |
| Volatile Matter | Thermogravimetric Analysis (TGA) | Mass loss measured upon heating to 150 C under nitrogen atmosphere, indicating low-boiling impurities and residual solvents. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification after acid digestion, based on atomic emission intensity at characteristic wavelengths. |
| Chloride Content | Potentiometric Titration with AgNO3 | Titration with silver nitrate using silver indicator electrode; endpoint detected by potential change due to AgCl precipitation. |
| Acid Number | Acid-Base Titration (NaOH in ethanol) | Neutralization of acidic impurities with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Sulfated Ash | Gravimetric Analysis (H2SO4 treatment + incineration) | Residue mass after sulfuric acid treatment followed by incineration at 700 C; indicates metal sulfates and non-volatile residues. |
| Organic Volatile Impurities | GC-FID | Separation and quantification of volatile organic compounds using capillary GC with flame ionization detection. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity pattern to determine volume-based particle size distribution in dispersed suspension. |
