Manufacturing Quality Control of 3-Hexyn-2,5-diol
| Test Item | Common Test Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color, state, and presence of impurities under natural light or standard lighting conditions. 3-Hexyne-2,5-diol should appear as a colorless to light yellow transparent liquid or crystalline solid. |
| Purity/Main Component Content | Gas Chromatography (GC) | Perform capillary column gas chromatography with an FID detector to quantitatively analyze the main peak area. Calculate the content of 3-hexyne-2,5-diol using external or internal standard methods to evaluate purity. |
| Water Content | Karl Fischer Titration | React the sample's water content quantitatively with Karl Fischer reagent. Determine water content by coulometric or volumetric titration to control product dryness. |
| Acid Value/Acidity | Acid-Base Titration | Using phenolphthalein as an indicator, titrate free acids in the sample with a standard sodium hydroxide solution. Calculate the acid value (mg KOH/g) to indicate the level of acidic impurities. |
| Residual Solvents | Gas Chromatography (GC) | Analyze possible residual organic solvents (e.g., methanol, acetone) from the manufacturing process using headspace or direct injection GC with FID or MS detectors for qualitative and quantitative analysis. |
| Heavy Metals | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) or Atomic Absorption Spectroscopy (AAS) | After sample digestion, use ICP-MS or AAS to determine levels of heavy metal elements such as lead, cadmium, mercury, and arsenic, ensuring compliance with safety limits. |
| Melting Point (if solid) | Melting Point Determination | Determine the melting temperature range using a melting point apparatus or capillary method. Compare with the standard melting point (approximately 70–74 °C) to assess purity and crystal form consistency. |
| Refractive Index (if liquid) | Refractometry | Measure the refractive index of the sample at a specified temperature (usually 20 °C or 25 °C) using an Abbe refractometer, as an auxiliary identification and purity indicator. |
