Manufacturing Quality Control of 3-BUTENE-1,2-DIOL
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID | Quantifies 1,4-butanediol content by separation and flame ionization detection relative to internal/external standard. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water and iodine in pyridine/methanol medium. |
| Acidity (as H2SO4) | Acid-Base Titration | Determines total acidic impurities by titration with standardized NaOH using phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Evaluates yellowness by comparing sample color to APHA platinum-cobalt standards at 455 nm. |
| Density at 20 C | Digital Density Meter | Measures mass per unit volume using oscillating U-tube principle calibrated with air/water. |
| Refractive Index at 20 C | Refractometry | Determines refractive index by measuring angle of light refraction at sodium D-line wavelength. |
| Residue on Evaporation | Gravimetric Analysis | Quantifies non-volatile residue after controlled evaporation and drying to constant weight. |
| Aldehydes (as acetaldehyde) | Spectrophotometry (DNPH Derivatization) | Measures aldehyde content via hydrazone formation with DNPH followed by UV-Vis absorbance at 360 nm. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals after wet digestion by atomic absorption at element-specific wavelengths. |
| Chloride Content | Potentiometric Titration with AgNO3 | Determines chloride ions by titration with silver nitrate using silver electrode endpoint detection. |
| Iron Content | ICP-OES | Measures iron concentration after acid digestion by detecting characteristic atomic emission lines. |
| Non-Volatile Matter | Gravimetric Analysis | Determines insoluble particulates by filtration, drying, and weighing of retained residue. |
