Manufacturing Quality Control of Diphenyldichloromethane
| 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 certified reference standard. |
| Related Substances | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and semi-quantifies impurities based on retention time and mass spectral fragmentation patterns. |
| Moisture Content | Karl Fischer Titration | Measures water content via stoichiometric iodine reaction with water in anhydrous methanol/pyridine medium. |
| Acid Value | Acid-Base Titration with NaOH standard solution | Determines free acidic impurities by titration with standardized sodium hydroxide in ethanol. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Measures non-volatile inorganic residue after high-temperature ashing at 700-800 C. |
| Heavy Metals | ICP-OES | Quantifies trace metal contaminants (e.g., Pb, Cd, Hg, As) by atomic emission intensity at characteristic wavelengths. |
| Chloride Content | Potentiometric Titration with AgNO3 | Detects chloride ions by measuring potential change during silver nitrate titration. |
| Melting Point | Capillary Melting Point Determination | Measures temperature range at which solid transitions to liquid using calibrated capillary apparatus. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of visible particulates or phase separation under controlled lighting. |
| Solubility in Common Solvents | Qualitative Solubility Test | Evaluates complete dissolution in specified solvents (e.g., toluene, chloroform) at room temperature. |
| Volatile Impurities | Headspace Gas Chromatography (HS-GC) | Detects low-boiling residual solvents (e.g., dichloromethane, acetone) via equilibrium vapor phase analysis. |
| Bulk Density | ASTM D1895 Method A (Tapped Density) | Determines mass per unit volume after standardized tapping; reflects powder flow and handling characteristics. |
