Manufacturing Quality Control of Oxybis(methyl-2,1-ethanediyl) diacrylate
| Test Item | Common Testing Method | Method Summary |
|---|---|---|
| Appearance | Visual Inspection | Observe the color, transparency, and presence of suspended particles or precipitates under natural light or a standard light source. Typically required to be a clear, colorless to light yellow liquid. |
| Color (Pt-Co) | Platinum-Cobalt Colorimetry (GB/T 3143 or ASTM D1209) | Compare the sample with standard platinum-cobalt solutions using visual inspection or a spectrophotometer to determine the color value, assessing product purity and oxidation level. |
| Purity/Main Content | Gas Chromatography (GC) or High-Performance Liquid Chromatography (HPLC) | Analyze the sample using GC or HPLC for separation. Quantify the main component content of dipropyleneglycol diacrylate via peak area normalization or external standard method, typically required to be ≥98.0%. |
| Acid Value | Titration Method (GB/T 601 or ASTM D974) | Use phenolphthalein as an indicator and titrate free acid in the sample with standardized potassium hydroxide ethanol solution to calculate the acid value (mg KOH/g), reflecting the level of residual acidic impurities. |
| Moisture | Karl Fischer Method (KF Method, GB/T 6283 or ASTM E1064) | Quantitatively react water in the sample with Karl Fischer reagent using coulometric or volumetric methods to determine moisture content, usually controlled at ≤0.1%. |
| Refractive Index | Refractometry (GB/T 614 or ASTM D1218) | Determine the refractive index of the sample at a specified temperature (e.g., 25°C) using an Abbe refractometer as an auxiliary identification and purity indicator. |
| Density | Densitometer Method or Pycnometer Method (GB/T 4472 or ASTM D4052) | Determine the density of the sample at a standard temperature for quality consistency control. |
| Inhibitor Content (e.g., HQ, MEHQ) | High-Performance Liquid Chromatography (HPLC) | Separate and quantify polymerization inhibitors (e.g., methylehydroquinone) in the sample using HPLC to ensure polymer stability, typical range is 100–300 ppm. |
| Hydroxyl Value (if applicable) | Acetylation Method (GB/T 7383 or ASTM D4274) | Perform acetylation reaction on samples potentially containing hydroxyl groups followed by titration to calculate the hydroxyl value, indirectly reflecting by-products or unreacted raw material residues. |
| Viscosity | Rotational Viscometer Method (GB/T 2794 or ASTM D2196) | Determine dynamic or kinematic viscosity at a specified temperature to assess processability and batch consistency. |
