Manufacturing Quality Control of 2,4-Xylenesulfonic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration | Quantifies sulfonic acid groups by neutralization with standardized NaOH solution using phenolphthalein indicator. |
| Moisture Content | Karl Fischer Titration | Determines water content via coulometric or volumetric reaction between water and iodine in a pyridine-methanol solvent system. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Measures yellowness intensity by comparing sample color to APHA platinum-cobalt standards or at 430 nm absorbance. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic impurities by ashing at 700-800 C and weighing residual mass. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals after wet digestion by measuring absorbance of atomized metal vapors at characteristic wavelengths. |
| Sulfate (SO4) | Barium Sulfate Gravimetry | Precipitates sulfate as BaSO4, filters, dries, and weighs the insoluble residue. |
| Chloride (Cl) | Potentiometric Titration with AgNO3 | Determines chloride concentration by titration with silver nitrate using a silver electrode for endpoint detection. |
| Iron (Fe) | ICP-OES | Quantifies iron after acid digestion by measuring emission intensity of Fe atomic lines in inductively coupled plasma. |
| Organic Impurities (Related Substances) | HPLC-UV | Separates and quantifies structurally related compounds (e.g., xylenes, mono-sulfonates) using reversed-phase chromatography and UV detection. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating purity and identity. |
| pH (1% aqueous solution) | pH Meter | Measures hydrogen ion activity in dilute aqueous suspension using calibrated glass electrode. |
| Bulk Density | Graduated Cylinder Method | Determines mass per unit volume by pouring sample into a calibrated cylinder and calculating density from weight and volume. |
