Manufacturing Quality Control of TRIPENTAERYTHRITOL
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Place the sample on a white background to observe color and physical state, determining whether it is a white crystalline powder and checking for impurities or caking. |
| Melting Point | Capillary Melting Point Determination | Heat the sample using a melting point apparatus or capillary method, recording the temperature range at which it fully melts, and compare with the standard value (approximately 260–265°C). |
| Content (Purity) | Acid-Base Titration / High-Performance Liquid Chromatography (HPLC) | Titration method: After acetylation followed by saponification, titrate the generated acetic acid with a standard base solution; HPLC method: Quantify the main peak area using a refractive index detector (RID) to calculate purity. |
| Water Content | Karl Fischer Titration | Quantitatively determine water content in the sample using an electrochemical reaction; suitable for trace moisture detection with high accuracy. |
| pH Value | pH Meter Method | Prepare an aqueous solution of pentaerythritol (e.g., 5% w/v) and measure its acidity/basicity using a calibrated pH meter; pH should typically be near neutral (pH 5–7). |
| Residue on Ignition (Sulfated Ash) | Gravimetric Method | Ignite the sample in a high-temperature muffle furnace until constant weight is achieved; weigh the residue to calculate ash content, reflecting levels of inorganic impurities. |
| Chlorides | Turbidimetry or Ion Chromatography | Turbidimetry: React with silver nitrate in nitric acid medium to form silver chloride turbidity, then measure by colorimetry; ion chromatography provides more precise quantification. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After sample digestion, determine the total content of heavy metal elements such as lead, cadmium, and mercury, ensuring compliance with pharmacopeial or industrial standard limits. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Separate potential by-products (e.g., trimethylolpropane, dipentaerythritol) using a reversed-phase chromatography column and detect impurity peaks. |
