Manufacturing Quality Control of Diethylene glycol monomethyl ether
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Place the sample in a transparent glass bottle and observe its color and clarity under natural light or standard illumination to determine whether it is a colorless, transparent liquid, and check for suspended particles or precipitates. |
| Color | Platinum-Cobalt Colorimetric Method (GB/T 3143 or APHA) | Use standard platinum-cobalt solutions for color comparison to measure the sample's color value (units: APHA or Hazen), assessing purity and degree of oxidation. |
| Purity (Main Component Content) | Gas Chromatography (GC) | Quantitative determination of methoxydiglycol (diethylene glycol monomethyl ether) content using capillary column gas chromatography with a flame ionization detector (FID), via internal or external standard method; offers high separation efficiency and accuracy. |
| Water Content | Karl Fischer Titration | Utilize Karl Fischer reagent to quantitatively react with water in the sample; determine moisture content by coulometric or volumetric titration. Suitable for trace moisture analysis. |
| Density | Densimeter or Pycnometer Method | Measure the mass-to-volume ratio of the sample at a specified temperature (e.g., 20°C) using a densimeter or pycnometer to calculate density, used to verify material consistency. |
| Refractive Index | Refractometry (Abbe Refractometer) | Measure the refractive index of the sample using an Abbe refractometer at a standard temperature (typically 20°C); serves as an auxiliary indicator for purity and composition. |
| Acid Value | Acid-Base Titration | Titrate free acids in the sample with a standardized potassium hydroxide ethanol solution; expressed as milligrams of KOH required to neutralize one gram of sample (mg KOH/g), used to evaluate oxidation or impurity levels. |
| Boiling Range (Distillation Range) | Distillation Method (GB/T 615) | Heat the sample using a standard distillation apparatus and record the initial and final boiling points to determine the boiling range, helping identify volatile impurities. |
| Impurity Analysis | Gas Chromatography-Mass Spectrometry (GC-MS) | Combine GC’s separation capability with MS’s identification power to detect and quantify organic impurities in the sample (e.g., ethylene glycol monomethyl ether, triethylene glycol, etc.). |
| pH Value (Aqueous Solution) | pH Meter Measurement | Prepare an aqueous solution of defined concentration (e.g., 10%), then measure its acidity or alkalinity using a calibrated pH meter to assess whether it is neutral, weakly acidic, or weakly basic. |
