Manufacturing Quality Control of Tri(propylene glycol) diacrylate
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color, clarity, and presence of impurities or suspended particles under natural light or standard illumination. |
| Color (Hazen Units) | Platinum-Cobalt Colorimetric Method (e.g., ASTM D1209) | Compare the sample with standard platinum-cobalt solutions to determine its yellow intensity, assessing purity and oxidation level. |
| Acid Value | Potentiometric Titration or Indicator Titration (e.g., GB/T 6365) | Titrate free acids in the sample using potassium hydroxide in ethanol solution, calculating the milligrams of KOH per gram of sample (mg KOH/g). |
| Hydroxyl Value | Acetylation Method (e.g., ASTM D4274) | Determine residual hydroxyl group content through acetylation reaction, reflecting the level of unreacted intermediates or impurities. |
| Moisture Content | Karl Fischer Titration | Quantitatively determine trace moisture in the sample using Karl Fischer reagent (typically <0.1%). |
| Purity/Main Component Content | Gas Chromatography (GC) or High-Performance Liquid Chromatography (HPLC) | Quantitatively analyze the area of the main peak of TPGDA via chromatography to assess product purity (typically ≥98%). |
| Residual Acrylate Monomers | Gas Chromatography (GC) | Detect unreacted acrylic acid, mono-acrylates, and other low-molecular-weight by-products to ensure polymerization activity and safety. |
| Inhibitor Content (e.g., HQ, MEHQ) | High-Performance Liquid Chromatography (HPLC) | Quantitatively determine the content of added inhibitors (e.g., monomethyl ether of hydroquinone), typically controlled at 50–200 ppm to prevent self-polymerization during storage. |
| Refractive Index | Abbé Refractometer Method (e.g., ASTM D1218) | Determine the refractive index at a specific temperature as an auxiliary identification and purity indicator. |
| Density | Density Meter or Specific Gravity Bottle Method (e.g., ASTM D1217) | Measure the density of the sample at a specified temperature for quality consistency control. |
| Viscosity | Rotational Viscometer Method (e.g., ASTM D2196) | Measure the dynamic viscosity at a specified temperature, reflecting molecular weight distribution and impurity effects. |
