Manufacturing Quality Control of Diallyl phthalate
| Test Item | Common Testing Method | Method Description |
|---|---|---|
| Appearance | Visual Inspection | Place the sample in a transparent container and observe its color, clarity, and presence of suspended particles or sediment under natural light or standard light sources. It is typically a clear to light yellow liquid. |
| Color (APHA) | Platinum-Cobalt Colorimetry (GB/T 3143 or ASTM D1209) | Compare the sample with standard platinum-cobalt solutions using colorimetric methods to assess the depth of color, indicating product purity and oxidation level. |
| Purity / Main Component Content | Gas Chromatography (GC) | Use a capillary column gas chromatograph to qualitatively identify compounds by retention time and quantitatively determine DAP purity using peak area normalization or external standard methods. |
| Acid Value | Acid-Base Titration (GB/T 6743 or ISO 2114) | Determine free acids in the sample by titrating with standardized potassium hydroxide ethanol solution, calculating the milligrams of KOH consumed per gram of sample to reflect acid impurity content. |
| Density | Densitometer or Pycnometer Method (GB/T 4472) | Measure the mass-to-volume ratio at a specified temperature (e.g., 25°C) using a densitometer or pycnometer for quality consistency control. |
| Refractive Index | Refractometry (GB/T 6488) | Measure the refractive index using an Abbe refractometer at a specified temperature as an auxiliary indicator for identification and purity assessment. |
| Moisture Content | Karl Fischer Titration (GB/T 6283) | Determine trace water content by reacting iodine and sulfur dioxide with water in a pyridine-methanol system, suitable for organic liquids. |
| Viscosity (Kinematic Viscosity) | Capillary Viscometer Method (GB/T 265 or ASTM D445) | Measure the time required for a specific volume of sample to flow through a capillary at constant temperature and calculate kinematic viscosity to evaluate fluidity. |
| Volatile Content | Thermogravimetric Analysis (TGA) or Oven Weight Loss Method | Heat the sample at a specified temperature for a set period, measure the weight difference before and after heating, and calculate volatile matter content. |
| Impurities (e.g., Monomers, By-products) | Gas Chromatography-Mass Spectrometry (GC-MS) | Couple the separation capability of GC with the structural identification ability of MS to qualitatively and quantitatively detect possible impurities such as monoallyl phthalate. |
