Manufacturing Quality Control of 1112-39-6
| Test Item | Common Test Method | Method Overview |
|---|---|---|
| Purity | Gas Chromatography (GC) | Capillary column is used to separate sample components, with FID detector for quantifying main component purity via area normalization or external standard method. |
| Moisture Content | Karl Fischer Titration | Utilizes the quantitative reaction of iodine and sulfur dioxide with water in a pyridine/methanol system; trace moisture is determined by potentiometric titration. |
| Density | Density Meter / Pycnometer Method | Sample density is measured using a digital density meter or pycnometer at a standard temperature (e.g., 20°C) to evaluate product consistency. |
| Refractive Index | Abbe Refractometer Method | Refractive index is measured at a specified temperature as an auxiliary parameter for identification and quality control. |
| Acid Value / Free Acid | Acid-Base Titration | Free acid is titrated with standardized sodium hydroxide solution using phenolphthalein as indicator to assess hydrolysis by-products or storage stability. |
| Color | Visual Color Comparison / Colorimeter | Sample color is compared visually with standard platinum-cobalt color solutions, or measured using a colorimeter to reflect impurity levels or degree of oxidation. |
| Volatile Residues | Gas Chromatography-Mass Spectrometry (GC-MS) | Separates and identifies volatile impurities (e.g., unreacted raw materials, by-products), used for process optimization and impurity control. |
| Hydrolytic Stability | Accelerated Hydrolysis Test + GC Analysis | Sample is subjected to controlled temperature and humidity conditions for hydrolysis; samples are taken periodically and analyzed by GC to determine residual main component, assessing storage stability. |
| Heavy Metal Content | Atomic Absorption Spectroscopy (AAS) | After digestion, AAS is used to measure content of harmful metal elements such as lead, arsenic, and mercury, ensuring compliance with safety standards. |
| Appearance and Physical State | Visual Inspection + Physical Observation | Observe whether the sample is a colorless, transparent liquid, free from suspended particles, precipitates, or phase separation, providing an initial assessment of physical quality. |
