Manufacturing Quality Control of DBE DIBASIC ESTER
| Test Item | Common Test Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Place the sample in a transparent container and observe its color, transparency, and the presence of suspended particles or sediment under natural light or a standard light source. |
| Color Intensity | Platinum-Cobalt Colorimetric Method (GB/T 3143) | Measure the color depth of liquid samples by comparison with standard platinum-cobalt solutions; suitable for light-colored organic liquids. |
| Ester Content | Gas Chromatography (GC) | Separate components in the sample using a gas chromatograph and quantify the target diester based on peak area, offering high resolution and accuracy. |
| Acid Value (Acidity) | Acid-Base Titration | Titrate free acids in the sample with a standardized sodium hydroxide solution; expressed as milligrams of KOH required to neutralize one gram of sample (mg KOH/g). |
| Water Content | Karl Fischer Method | Based on the quantitative reaction of iodine with sulfur dioxide in methanol in the presence of water; trace moisture is precisely determined via coulometric or volumetric titration. |
| Density | Densimeter Method or Pycnometer Method | Direct measurement using a densimeter, or determining mass per unit volume with a pycnometer at a specified temperature (e.g., 20°C). |
| Refractive Index | Refractometry | Measure the refractive index of the sample using an Abbe refractometer at a standard temperature (typically 20°C), used for component identification and purity assessment. |
| Purity (Total Impurities) | High-Performance Liquid Chromatography (HPLC) or GC | Separate and quantify the main component and impurity peaks; total purity is calculated using the normalization method, suitable for high-boiling-point or thermally unstable diesters. |
| Boiling Range / Boiling Point | Distillation Method | Determine initial and final boiling points using a standard distillation apparatus to assess volatility and component distribution, indicating fraction concentration. |
| Viscosity | Rotational Viscometer Method or Capillary Viscometer Method | Measure the resistance of a liquid to flow, evaluating its processability; typically conducted at a specified temperature (e.g., 25°C). |
