Manufacturing Quality Control of METHYLSUCCINIC ANHYDRIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration | Quantifies active anhydride groups by hydrolysis with standardized NaOH and back-titration with HCl. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric reaction between water, iodine, and sulfur dioxide in pyridine/methanol medium. |
| Acid Number | Acid-Base Titration | Determines total acidic impurities by titration with standardized KOH in ethanol. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Compares sample color to APHA platinum-cobalt standard solutions at 455 nm using calibrated spectrophotometer. |
| Density | Digital Density Meter | Measures mass per unit volume at specified temperature (e.g., 20 C) using oscillating U-tube principle. |
| Refractive Index | Refractometry | Determines ratio of light velocity in air vs. sample using Abbe refractometer at specified wavelength (589 nm) and temperature. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after controlled high-temperature ashing and weighing. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies trace metal contaminants by measuring absorption of characteristic wavelength light by ground-state atoms in flame. |
| Chloride Content | Potentiometric Titration | Detects chloride ions via titration with silver nitrate using silver indicator electrode and reference electrode. |
| Residual Solvents (e.g., toluene, xylene) | Gas Chromatography (GC-FID) | Separates and quantifies volatile organic impurities using capillary column and flame ionization detection. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated heating block and visual observation. |
| Appearance | Visual Inspection | Assesses physical state, clarity, and presence of suspended particles or phase separation under controlled lighting conditions. |
