Industrial Applications of 1,2-ETHANEDISULFONIC ACID DISODIUM SALT
| Industry | Application | Process |
|---|---|---|
| Chemical Synthesis | Used as an organic synthesis intermediate for preparing sulfonic acid-functionalized compounds | Sulfonic acid groups are introduced via sulfonation or combined esterification-sulfonation |
| Surfactants | Employed as a structural unit in anionic surfactants to enhance water solubility and wetting performance | Double sulfonate structures are constructed through nucleophilic substitution with fatty amines or alcohols |
| Dye Industry | Applied as a water-solubilizing modifier in dye molecules to improve aqueous dispersion | Disodium disulfonate groups are introduced via sulfonation in the final stage of dye synthesis |
| Electrochemistry | Used as an electrolyte additive to improve ionic conductivity | Added directly as a co-electrolyte component in battery electrolytes or electroplating baths |
Manufacturing Quality Control of 1,2-ETHANEDISULFONIC ACID DISODIUM SALT
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration | Quantifies active ingredient by titration with standardized HCl using bromocresol green indicator. |
| Sodium Content | Flame Photometry | Measures sodium emission intensity at 589 nm in atomized sample solution. |
| Sulfonate Group Content | Ion Chromatography (IC) | Separates and quantifies sulfonate anions using conductivity detection after ion exchange. |
| Water Content | Karl Fischer Titration | Determines water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Measures hydrogen ion activity using calibrated glass electrode in 1% w/v aqueous solution. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals by measuring absorbance of ground-state atoms at characteristic wavelengths. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Detects chloride ions by titration with silver nitrate using silver indicator electrode. |
| Sulfate Impurity | Gravimetric Analysis | Precipitates sulfate as BaSO4 and determines mass after drying and weighing. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing at 700-800 C. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of visible particulates or discoloration against white background. |
| Solubility in Water | Qualitative Dissolution Test | Evaluates complete dissolution of specified amount in distilled water at 25 C with gentle agitation. |
| Bulk Density | Volumetric Measurement | Determines mass per unit volume using standardized graduated cylinder and tapping procedure. |
