Manufacturing Quality Control of Propyl heptanoate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies庚酸丙酯 peak area relative to internal/external standard using calibrated response factors. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between iodine, sulfur dioxide, and water in methanol-based reagent. |
| Acid Value | Acid-Base Titration with NaOH | Determines free acid content by titrating carboxylic acid impurities with standardized sodium hydroxide solution. |
| Ester Value | Saponification followed by Acid-Base Titration | Measures total ester content by alkaline hydrolysis and back-titration of excess alkali. |
| Refractive Index | Refractometry at 20 degrees C | Determines refractive index using a calibrated Abbe refractometer based on light refraction angle. |
| Specific Gravity | Digital Density Meter or Pycnometer | Measures mass per unit volume relative to water at specified temperature. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement | Evaluates yellowness by comparing sample color to platinum-cobalt standard solutions. |
| Residue on Evaporation | Gravimetric Analysis | Measures non-volatile residue after controlled evaporation and drying under vacuum. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals by atomizing sample and measuring absorption of characteristic wavelength light. |
| Residual Solvents | Gas Chromatography (GC) with Headspace Sampling | Identifies and quantifies volatile organic solvents using equilibrium headspace gas analysis. |
| Peroxide Value | Iodometric Titration | Measures hydroperoxides by oxidation of iodide to iodine, followed by thiosulfate titration. |
| Non-Volatile Matter | Gravimetric Analysis | Determines insoluble particulates by filtration, drying, and weighing of retained residue. |
