Manufacturing Quality Control of Propylene carbonate
| Test Item | Common Test Method | Method Overview |
|---|---|---|
| Purity | Gas Chromatography (GC) | Uses capillary column gas chromatography to determine the content of the main component by comparing retention times with standard substances and applying the peak area normalization method, thereby assessing product purity. |
| Moisture Content | Karl Fischer Titration | Utilizes the quantitative reaction of iodine with sulfur dioxide in a pyridine/methanol system with water; moisture content is determined by potentiometric or dead-stop endpoint detection. |
| Color | Platinum-Cobalt Colorimetric Method (Hazen Method) | Compares the sample visually or by spectrophotometry against standard platinum-cobalt solutions; color intensity is expressed in Hazen units (Pt-Co). |
| Density | Density Meter or Oscillating U-tube Method | Measures sample density at a specified temperature (e.g., 20°C) using a glass hydrometer or digital oscillating U-tube densitometer, serving as an auxiliary indicator of purity. |
| Refractive Index | Abbe Refractometry | Measures the refractive index of the sample for sodium D-line light under constant temperature conditions (typically 20°C or 25°C) using an Abbe refractometer, reflecting consistency in chemical composition. |
| Acid Value | Acid-Base Titration | Titrates free acids in the sample with a standard potassium hydroxide ethanol solution using phenolphthalein as indicator; acid value is expressed as milligrams of KOH consumed per gram of sample (mg KOH/g). |
| Evaporation Residue | Gravimetric Method | A known quantity of sample is evaporated to dryness at a specified temperature, and the residue is weighed to evaluate the content of non-volatile impurities. |
| Chloride Content | Silver Nitrate Turbidity Method or Ion Chromatography | Quantifies chloride ions either by turbidity from the white precipitate formed when silver nitrate reacts with chloride ions, or by ion chromatographic separation followed by conductivity detection for trace chloride analysis. |
| Heavy Metal Content | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After sample digestion, determines concentrations of heavy metal elements such as lead, cadmium, mercury, and arsenic using atomic absorption spectroscopy or inductively coupled plasma mass spectrometry (ICP-MS). |
| Peroxides | Iodometric Method | In acidic conditions, peroxides oxidize potassium iodide to release iodine, which is then titrated with a standard sodium thiosulfate solution; peroxide content is calculated based on the titration result. |
