Manufacturing Quality Control of 1,3-Dimercaptopropane
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID | Quantifies 1,3-propanedithiol by separation and flame ionization detection relative to a certified reference standard. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration using iodine-based redox reaction in anhydrous methanol/pyridine medium. |
| Acidity (as H2SO4) | Acid-Base Titration | Determines total acidic impurities by titration with standardized NaOH solution using phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Evaluates yellowness by comparing sample color to APHA platinum-cobalt standards or measuring absorbance at 430 nm. |
| Density at 20 C | Digital Density Meter | Measures mass per unit volume using oscillating U-tube principle calibrated with water and air. |
| Refractive Index at 20 C | Refractometry | Determines refractive index by measuring angle of light refraction at sodium D-line wavelength using calibrated prism. |
| Sulfur Content | Combustion IC Analysis | Oxidizes organic sulfur to SO2, followed by conductivity detection of sulfate in aqueous absorption solution. |
| Residue on Evaporation | Gravimetric Analysis | Measures non-volatile residue after controlled evaporation under nitrogen and drying to constant weight. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies trace metals after acid digestion and chelation, using hollow cathode lamp absorption at element-specific wavelength. |
| Chloride Content | Potentiometric Titration with AgNO3 | Detects chloride ions by silver nitrate titration monitored with silver indicator electrode. |
| Odor Impurities (qualitative) | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies volatile odor-causing impurities (e.g., mercaptans, sulfides) via retention time and mass spectral matching. |
| Flash Point | Tag Closed Cup Tester | Determines lowest temperature at which vapor forms ignitable mixture with air under standardized closed-cup conditions. |
