Manufacturing Quality Control of Ethanesulfonyl chloride
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Ethylsulfonyl Chloride Content) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard using a polar capillary column. |
| Acidity (as HCl) | Acid-Base Titration with NaOH and phenolphthalein indicator | Neutralization of acidic impurities (e.g., residual HCl, sulfonic acids) by standardized sodium hydroxide solution. |
| Moisture Content | Karl Fischer Coulometric Titration | Electrochemical quantification of water via iodine generation and stoichiometric reaction with water in anhydrous methanol medium. |
| Residual Solvents (e.g., dichloromethane, ethanol) | Gas Chromatography (GC) with Headspace sampling | Separation and quantification of volatile solvents using headspace injection and flame ionization detection. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 455 nm | Evaluation of yellowish discoloration by comparing absorbance at 455 nm to platinum-cobalt standards. |
| Density at 20 degC | Digital Density Meter (Oscillating U-tube principle) | Measurement of mass per unit volume based on resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Refractive Index at 20 degC | Abbe Refractometer | Determination of light bending angle at air-sample interface to infer purity and composition. |
| Chloride Ion (Cl-) | Ion Chromatography (IC) with conductivity detection | Separation of anions on an ion-exchange column followed by quantitative detection via electrical conductivity. |
| Sulfate Ion (SO42-) | Ion Chromatography (IC) with conductivity detection | Anion separation and conductivity-based quantification after suppression of background electrolyte. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) after wet digestion | Quantification of trace metals following acid digestion and atomization in graphite furnace or flame. |
| Non-Volatile Residue | Gravimetric Analysis (Evaporation and Weighing) | Determination of residue left after controlled evaporation of a known sample mass under specified temperature and time. |
| Peroxide Value | Iodometric Titration | Oxidation of potassium iodide by peroxides to liberate iodine, titrated with standardized sodium thiosulfate. |
