Manufacturing Quality Control of Isostearic Acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Acid Value | Acid-Base Titration | Neutralization of carboxylic acid groups with standardized KOH solution using phenolphthalein indicator. |
| Iodine Value | Wijs Method | Addition of excess iodine monochloride to double bonds, followed by titration of unreacted iodine with sodium thiosulfate. |
| Saponification Value | Acid-Base Titration | Hydrolysis of esters with excess KOH, then back-titration of unreacted alkali with HCl. |
| Peroxide Value | Iodometric Titration | Oxidation of potassium iodide by peroxides to liberate iodine, titrated with sodium thiosulfate. |
| Color (Gardner Scale) | Visual Comparison or Spectrophotometry | Comparison of sample color against standard Gardner color scale under controlled lighting conditions. |
| Moisture Content | Karl Fischer Titration | Quantitative reaction of water with iodine and sulfur dioxide in pyridine/methanol medium, monitored potentiometrically. |
| Unsaponifiable Matter | Solvent Extraction and Gravimetry | Extraction with diethyl ether after alkaline hydrolysis, followed by solvent evaporation and residue weighing. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Atomization of digested sample and measurement of absorbance at characteristic wavelength for lead. |
| Residual Solvents (e.g., hexane) | Gas Chromatography (GC) | Separation and quantification of volatile solvents using flame ionization detection. |
| Melting Point | Capillary Melting Point Apparatus | Observation of temperature range over which solid transitions to liquid in a calibrated capillary tube. |
| Assay (Purity) | Gas Chromatography (GC) with Internal Standard | Quantification of main component relative to internal standard using peak area ratios. |
| Free Fatty Acid Profile | Gas Chromatography-Mass Spectrometry (GC-MS) | Derivatization to methyl esters, separation by GC, and identification/quantification via mass spectral fragmentation. |
