Manufacturing Quality Control of ETHYL STEARATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) | Quantifies十八酸乙酯 peak area relative to internal/external standard using flame ionization detection. |
| Acid Value | Acid-Base Titration | Measures free fatty acids by titration with standardized KOH solution in alcoholic medium. |
| Saponification Value | Acid-Base Titration | Determines total ester content via alkaline hydrolysis followed by back-titration of excess KOH. |
| Iodine Value | Wijs Method (Titration) | Measures unsaturation by addition of iodine monochloride to double bonds, followed by iodometric titration. |
| Water Content | Karl Fischer Titration | Electrochemically quantifies water via reaction of iodine, sulfur dioxide, and water in pyridine/methanol medium. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Compares sample color to APHA platinum-cobalt standard solutions at 455 nm or by visual assessment. |
| Refractive Index | Refractometry | Measures bending of light through liquid sample at specified temperature (e.g., 20 C) using calibrated refractometer. |
| Density | Pycnometry or Digital Density Meter | Determines mass per unit volume at controlled temperature using calibrated glass pycnometer or oscillating U-tube principle. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic impurities by ashing sample at 600-800 C and weighing residual ash. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies trace heavy metals after acid digestion and chelation, using hollow cathode lamp absorption. |
| Non-Volatile Residue | Gravimetric Analysis | Determines residue after evaporation of fixed volume under controlled heating and drying conditions. |
| Odor | Sensory Evaluation | Assesses presence of off-odor by trained personnel against specification; pass/fail based on typical fatty ester character. |
