Manufacturing Quality Control of Dipropylene Glycol Dimethyl Ether
| Test Item | Common Test Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample under natural or standard lighting to check if it is a colorless, transparent liquid, and inspect for any suspended matter, sediment, or foreign materials. |
| Color | Platinum-Cobalt Colorimetric Method (GB/T 3143 or ASTM D1209) | Compare the sample with standard platinum-cobalt solutions to determine its color intensity, expressed in Hazen (platinum-cobalt) units. |
| Density | Density Meter Method or Digital Density Measurement (GB/T 2013 or ASTM D4052) | Measure the sample's density at a specified temperature (usually 20 °C) to assess purity and impurity levels. |
| Refractive Index | Abbe Refractometer Method (GB/T 614 or ASTM D1218) | Measure the sample's refractive index for sodium light (589.3 nm) at a standard temperature, reflecting the substance's purity and compositional consistency. |
| Water Content | Karl Fischer Coulometric or Volumetric Method (GB/T 6283 or ASTM E1064) | Use Karl Fischer reagent to quantitatively react with water in the sample to accurately determine trace moisture content. |
| Purity/Main Component Content | Gas Chromatography (GC, e.g., GB/T 9722 or ASTM D6730) | Use capillary column gas chromatography to separate sample components and determine the content of dipropylene glycol dimethyl ether by area normalization or internal standard method. |
| Acid Value | Acid-Base Titration (GB/T 7304 or ASTM D974) | Titrate acidic substances in the sample with potassium hydroxide ethanol solution; results are expressed in mg KOH/g to evaluate acidic impurity levels. |
| Evaporation Residue | Gravimetric Method | Weigh the residue left after evaporating a known quantity of the sample under specified conditions to reflect the content of non-volatile impurities. |
| Boiling Range | Distillation Method (GB/T 7534 or ASTM D86) | Determine the temperature range from initial to final boiling points using a standard distillation apparatus to evaluate component uniformity and impurity levels. |
| Peroxides | Iodometric or Colorimetric Method | Oxidize iodide ions with peroxides to produce iodine, which is then titrated with sodium thiosulfate or measured colorimetrically to assess oxidation stability risk. |
