Manufacturing Quality Control of 2,2-Dimethyl-1,3-propanediol
| Test Item | Common Test Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color and physical state of the sample; typically it should be white crystals or powder, free from visible impurities. |
| Purity | Gas Chromatography (GC) | Separation using a capillary column with FID detection; quantify main component content by area normalization or external standard method. |
| Melting Point | Capillary Melting Point Method | Determine the temperature range from initial melting to complete liquefaction using a melting point apparatus; standard value is approximately 124–130°C. |
| Hydroxyl Value | Acetylation Method (ASTM E222 or similar) | React with acetic anhydride, then hydrolyze and titrate with standard KOH solution to calculate milliequivalents of hydroxyl groups per gram of sample. |
| Moisture Content | Karl Fischer Titration (KF Method) | Determine trace water content using coulometric or volumetric method to ensure compliance with dry material requirements (typically <0.2%). |
| Acid Value | Acid-Base Titration | Titrate free acids with standard potassium hydroxide in ethanol solution; express as mg KOH/g to indicate acidic impurity levels. |
| Color | Platinum-Cobalt Colorimetric Method (APHA/Hazen) | Compare sample solution color with standard platinum-cobalt solutions to assess color intensity, indicating degree of oxidation or impurities. |
| Ash Content | High-Temperature Ignition Method | Ignite the sample in a high-temperature furnace (e.g., 750°C), weigh the residue, and calculate ash content to evaluate inorganic impurity levels. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After digestion, measure concentrations of harmful metal elements such as lead, arsenic, and mercury to ensure compliance with pharmacopoeial or industry limits. |
| Volatile Organic Compounds (VOCs) | Headspace-Gas Chromatography (HS-GC) | Analyze residual solvents or volatile impurities (e.g., methanol, acetone) using headspace sampling coupled with GC. |
| Crystallization Point / Freezing Point | Freezing Point Analyzer | Measure the temperature at which crystals begin to form during cooling of a liquid sample; indirectly reflects purity. |
