Manufacturing Quality Control of METHYL HEPTADECANOATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID | Quantitative determination based on peak area comparison against a certified reference standard using a non-polar capillary column. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration where iodine is generated in situ to react stoichiometrically with water; endpoint detected amperometrically. |
| Acid Value | Acid-Base Titration (NaOH in ethanol) | Neutralization of free carboxylic acid groups with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Ester Value | Saponification followed by Acid-Base Titration | Complete alkaline hydrolysis of ester, followed by back-titration of excess alkali with standardized HCl. |
| Refractive Index | Refractometry (20 C) | Measurement of light bending angle at air-sample interface using calibrated Abbe refractometer; correlates with molecular composition and purity. |
| Color (APHA) | Visual Comparison or Spectrophotometric (430 nm) | Comparison of sample color intensity against platinum-cobalt standard solutions or absorbance measurement at 430 nm. |
| Density (20 C) | Digital Density Meter or Pycnometer | Mass-to-volume ratio determined by oscillating U-tube principle or calibrated glass pycnometer at controlled temperature. |
| Residue on Ignition | Gravimetric Analysis | Heating sample to 700-800 C to volatilize organic matter, then weighing inorganic residue after cooling in desiccator. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of metal content after acid digestion and matrix-matched calibration using hollow cathode lamp absorption. |
| Residual Methanol | Gas Chromatography (GC) with FID | Direct injection and separation on polar column (e.g., DB-WAX), quantified via external calibration curve. |
| Peroxide Value | Iodometric Titration | Oxidation of potassium iodide by peroxides to liberate iodine, titrated with standardized sodium thiosulfate. |
| Non-Volatile Residue | Evaporation and Gravimetry | Evaporation of known sample mass under controlled conditions (e.g., 105 C, 2 h), followed by weighing of residual material. |
