Manufacturing Quality Control of HEXANOIC ANHYDRIDE
| Test Item | Common Test Method | Method Summary |
|---|---|---|
| Appearance | Visual Inspection | Place the sample in a clean, colorless, transparent glass bottle and observe its color, transparency, and presence of mechanical impurities under natural light. |
| Content (Purity) | Gas Chromatography (GC) | Use a capillary gas chromatograph with an appropriate internal or external standard method to measure the peak area of hexanoic anhydride and calculate its purity. |
| Acid Value (Free Acid) | Acid-Base Titration | Titrate the free hexanoic acid in the sample with a standard ethanol solution of sodium hydroxide, using phenolphthalein as indicator, and calculate the acid value (mg KOH/g). |
| Moisture Content | Karl Fischer Titration | Use Karl Fischer reagent to accurately determine trace moisture content in the sample by coulometric or volumetric methods. |
| Density | Densimeter or Pycnometer Method | Measure the density of the sample at a specified temperature (e.g., 20°C) using a densimeter or pycnometer. |
| Refractive Index | Refractometry | Determine the refractive index of the sample using an Abbe refractometer at a standard temperature (e.g., 20°C), used for auxiliary identification and purity assessment. |
| Color | Platinum-Cobalt Colorimetric Method | Compare the sample with a platinum-cobalt standard color scale to evaluate its color intensity, reflecting impurity levels or degree of oxidation. |
| Volatile Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Separate and identify potential low-boiling-point impurities or residual solvents in the sample for high-purity analysis. |
| Thermal Stability | Thermogravimetric Analysis (TGA) | Measure mass changes of the sample under programmed temperature conditions to evaluate its decomposition temperature and thermal stability. |
