Manufacturing Quality Control of Propyl propionate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID | Quantitative separation and detection of丙酸正丙酯 based on retention time and peak area relative to a certified reference standard. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based solvent system. |
| Acidity (as Acetic Acid) | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Measurement of yellowness by comparing sample absorbance at 430 nm to APHA color standards. |
| Density at 20 C | Digital Density Meter | Determination of mass per unit volume using oscillating U-tube principle calibrated with air and water. |
| Refractive Index at 20 C | Refractometry | Measurement of light bending angle at air-sample interface using calibrated Abbe refractometer. |
| Distillation Range | Simple Distillation per ASTM D1078 | Temperature interval between initial boiling point and 95% recovery point under controlled heating and atmospheric pressure. |
| Residue on Evaporation | Gravimetric Analysis | Evaporation of a measured sample under controlled conditions followed by weighing of non-volatile residue. |
| Ester Value | Saponification Titration | Hydrolysis with excess KOH, followed by back-titration of unreacted alkali with HCl to determine ester content. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of metal impurities after acid digestion and atomization in flame or graphite furnace. |
| Non-Volatile Residue | Weight Loss on Heating | Heating a weighed sample to 105 C until constant weight and calculating residue as percentage of original mass. |
| Aldehyde Impurities | UV-Vis Spectrophotometry after Derivatization | Reaction with 2,4-dinitrophenylhydrazine to form hydrazones, followed by absorbance measurement at ~450 nm. |
