Manufacturing Quality Control of ETHYL UNDECANOATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies十一酸乙酯 peak area against a calibration curve using an internal or external standard. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration based on the iodine-sulfur dioxide reaction in pyridine-methanol medium. |
| Acid Value | Acid-Base Titration with NaOH | Determines free carboxylic acid content by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Ester Value | Saponification Titration followed by back-titration | Measures total ester content by saponification with excess KOH, then back-titrating unreacted alkali with HCl. |
| Refractive Index | Refractometry at 20 C | Determines ratio of light velocity in air vs. sample using calibrated refractometer; correlates with purity and composition. |
| Density | Digital Density Meter or Pycnometer | Measures mass per unit volume at specified temperature (e.g., 20 C) for batch consistency and identity verification. |
| Color (APHA) | Visual Comparison or Spectrophotometric APHA method | Evaluates yellowness intensity by matching sample color to platinum-cobalt standard solutions or measuring absorbance at 455 nm. |
| Residue on Ignition | Gravimetric Analysis after High-Temperature Ashing | Measures non-volatile inorganic impurities by weighing residue remaining after incineration at 700-800 C. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals by atomizing ashed sample and measuring absorption of characteristic wavelength light. |
| Chlorinated Solvent Residues | Gas Chromatography with ECD or MS detection | Detects and quantifies residual chlorinated solvents (e.g., chloroform, DCM) using selective electron capture or mass spectrometric detection. |
| Peroxide Value | Iodometric Titration | Measures hydroperoxides by their oxidation of iodide to iodine under acidic conditions, followed by thiosulfate titration. |
| Non-Volatile Residue | Gravimetric Evaporation | Determines volatile loss by evaporating known sample mass at 105 C and weighing residual non-volatile matter. |
