Manufacturing Quality Control of N,N'-Dimethyl-1,3-propanediamine
| Test Item | Common Test Method | Method Summary |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color, state, and presence of impurities under natural or standard lighting. It should be a colorless to pale yellow transparent liquid. |
| Color (Hazen) | Platinum-Cobalt Colorimetric Method (GB/T 3143 or ASTM D1209) | Compare the sample with standard platinum-cobalt color solutions to determine its color value in Hazen units, used to assess product purity and degree of oxidation. |
| Assay (Main Component Purity) | Gas Chromatography (GC) | Use capillary column GC with FID detector; quantify N,N'-dimethyl-1,3-propanediamine using internal standard or area normalization method. Typical purity ≥98.0%. |
| Water Content | Karl Fischer Titration (KF, GB/T 6283 or ASTM E1064) | Determine water content by quantitative reaction between Karl Fischer reagent and water, using either coulometric or volumetric titration. Typically ≤0.5%. |
| pH Value | pH Meter Method | Prepare an aqueous solution (e.g., 10%) and measure its pH using a calibrated pH meter to indicate levels of free amine or acidic/basic impurities. |
| Amine Value | Acid-Base Titration (ASTM D2074 or similar standards) | Titrate total amine groups in the sample with standardized hydrochloric acid solution and calculate amine value (mg KOH/g), indicating effective amine content. |
| Volatile Organic Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Use GC-MS for qualitative and semi-quantitative analysis of potential low-boiling by-products such as dimethylamine and 1,3-propanediamine. |
| Density | Densitometer or Pycnometer Method (GB/T 4472) | Measure the density of the sample at a specified temperature (e.g., 20°C) as an auxiliary quality control parameter. |
| Refractive Index | Abbe Refractometer Method (GB/T 614) | Measure refractive index at 20°C (nD20) for rapid identification and preliminary purity assessment. |
