Manufacturing Quality Control of Dimethyl thio-toluene diamine
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Place the sample in a clean, transparent container and visually examine its color and condition under natural light or standard illumination. Determine if it is a clear liquid ranging from pale yellow to amber, and check for turbidity, sediment, or suspended particles. |
| Purity (Content) | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with a UV detector (typically at 254 nm or 280 nm). Employ a water-organic solvent (e.g., methanol or acetonitrile) gradient elution. Quantify the DMTDA content by comparing retention time and peak area with a standard reference. |
| Moisture Content | Karl Fischer Titration | This method uses iodine and sulfur dioxide in a methanol-pyridine system to react quantitatively with water. The moisture content is determined using either coulometric or volumetric methods, suitable for detecting trace amounts of water. |
| Color | Platinum-Cobalt Colorimetry (Pt-Co Scale) | Compare the sample with standard platinum-cobalt solutions using visual or instrumental colorimetry to determine the color value (unit: Hazen or APHA), used to assess the refining degree of the product. |
| Density | Density Meter or Specific Gravity Bottle Method | Measure the mass per unit volume at a specified temperature (e.g., 25°C) using a density meter or specific gravity bottle to calculate density, used to assist in assessing purity and consistency of the substance. |
| pH Value (Solution) | pH Meter Measurement | Prepare a solution of DMTDA at a certain concentration (e.g., 1% aqueous solution) and measure its acidity or alkalinity using a calibrated pH meter to evaluate its stability and impurity effects. |
| Impurity Analysis | Gas Chromatography-Mass Spectrometry (GC-MS) or HPLC-MS | Analyze organic impurities (such as unreacted raw materials, by-products, or degradation products) in the sample for qualitative and quantitative identification, enhancing the ability to detect impurities. |
| Melting Point / Freezing Point | Melting Point Apparatus Method | DMTDA is usually a liquid at room temperature, but its freezing point can be measured. Use an automated melting point apparatus to gradually cool the sample and record the temperature at which solid begins to form, used to assess purity. |
| Sulfur Content | Elemental Analysis (e.g., Combustion-Infrared Absorption Method) | High-temperature combustion of the sample releases sulfur-containing gases, which are then detected by an infrared detector to determine total sulfur content, verifying whether the sulfur content matches the theoretical value. |
| Volatiles or Residual Solvents | Gas Chromatography (GC) | Use headspace-GC to detect residual organic solvents (e.g., toluene, methanol) from the production process, ensuring compliance with safety standards. |
