Manufacturing Quality Control of 3,4,9,10-Perylenetetracarboxylic dianhydride
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration with NaOH | Quantifies anhydride content via hydrolysis to tetracarboxylic acid followed by titration with standardized sodium hydroxide solution. |
| Moisture Content | Karl Fischer Titration | Measures water content based on the stoichiometric reaction of water with iodine and sulfur dioxide in a methanolic pyridine medium. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by high-temperature incineration followed by weighing of residual inorganic material. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals after wet digestion by measuring absorbance of ground-state atoms at characteristic wavelengths. |
| Iron (Fe) Content | Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) | Measures iron concentration by detecting element-specific emission lines from plasma-excited atoms. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Sulfate Impurity | Ion Chromatography (IC) | Separates and quantifies sulfate ions using anion-exchange column and conductivity detection. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating purity and identity. |
| Organic Volatile Impurities | Gas Chromatography (GC) with FID | Separates and quantifies residual solvents or low-MW impurities using capillary column and flame ionization detection. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement | Evaluates yellowness/brownness by comparing sample color to APHA platinum-cobalt standard solutions. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution of solid particles by analyzing angular variation in laser light scattering. |
| Bulk Density | Graduated Cylinder Method | Determines mass per unit volume of freely settled powder under standardized tapping conditions. |
