Manufacturing Quality Control of Diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide
| Detection Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Place the sample on a white background and observe under natural light or standard lighting for color, physical state, and presence of impurities. TPO typically appears as a white to slightly yellow powder. |
| Content (Purity) | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with UV detection (e.g., 254 nm). The peak area of TPO is compared with that of a reference standard to calculate its content. |
| Solubility | Dissolution Test | Take a certain amount of sample and add it to common solvents (e.g., ethanol, acetone, ethyl acetate, toluene), shake, and observe solubility to evaluate dissolving performance. |
| Melting Point | Melting Point Determination (Capillary Method or DSC) | Measure the melting temperature using a melting point apparatus or differential scanning calorimetry (DSC). The standard melting point of TPO is approximately 80–83°C. |
| Moisture Content | Karl Fischer Titration | Use Karl Fischer reagent to titrate moisture in the sample, accurately measuring residual water content, which should be kept below 0.5%. |
| Volatile Matter | Thermogravimetric Analysis (TGA) or Oven Method | Heat the sample at a specified temperature (e.g., 105°C) for a set time and measure weight loss to assess volatile impurity levels. |
| Heavy Metal Content | Atomic Absorption Spectroscopy (AAS) or ICP-MS | Digest the sample and detect trace heavy metals such as lead, mercury, cadmium, and chromium using AAS or inductively coupled plasma mass spectrometry (ICP-MS). |
| Organic Impurities / By-products | Gas Chromatography-Mass Spectrometry (GC-MS) or HPLC-MS | Analyze potential by-products or degradation products (e.g., trimethylbenzaldehyde, diphenyl phosphine oxide) to ensure total impurities meet specifications. |
| Photoinitiating Activity | Curing Performance Test (e.g., Real-time FTIR Monitoring) | Under simulated application conditions (e.g., UV irradiation), monitor double bond conversion rate in real time using Fourier-transform infrared spectroscopy (FTIR) to evaluate initiation efficiency. |
| Particle Size Distribution | Laser Particle Size Analysis | Disperse the sample in an appropriate medium and use laser scattering principles to determine particle size and distribution, suitable for powdered TPO. |
