Manufacturing Quality Control of ethane-1,2-diyl palmitate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard using a non-polar capillary column. |
| Acid Value | Acid-Base Titration with KOH in ethanol | Neutralization of free carboxylic acid groups by standardized potassium hydroxide solution, using phenolphthalein indicator. |
| Saponification Value | Back Titration after alkaline hydrolysis | Hydrolysis with excess KOH followed by titration of unreacted alkali to determine total ester content. |
| Iodine Value | Wijs method (titration with iodine monochloride) | Addition of known excess of ICl to double bonds, followed by titration of unreacted iodine with sodium thiosulfate. |
| Water Content | Karl Fischer Coulometric Titration | Electrochemical generation and titration of iodine with water in anhydrous methanol-based reagent. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 455 nm | Comparison of sample color intensity against platinum-cobalt standards or absorbance measurement at specified wavelength. |
| Refractive Index | Refractometry at 20 degrees C | Measurement of light bending angle through the sample using a calibrated Abbe refractometer. |
| Density | Digital Density Meter at 20 degrees C | Determination of mass per unit volume using oscillating U-tube principle. |
| Residue on Ignition | Gravimetric Analysis after High-Temperature Ashing | Heating to 750 degrees C to volatilize organic matter, then weighing inorganic residue. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) after wet digestion | Acid digestion followed by quantification of metal ions via absorption of characteristic atomic spectral lines. |
| Peroxide Value | Iodometric Titration | Oxidation of potassium iodide by peroxides to liberate iodine, titrated with sodium thiosulfate. |
| Non-Volatile Residue | Weight Loss on Drying (Gravimetric) | Evaporation of volatile components at 105 degrees C followed by weighing of residual material. |
