Manufacturing Quality Control of Diethyl malonate
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color, clarity, and presence of suspended particles or precipitates under natural light or standard light source. |
| Identification | Fourier Transform Infrared Spectroscopy (FT-IR) | Determine characteristic absorption peaks using an infrared spectrometer and compare with standard spectra to confirm the compound structure. |
| Content Determination | Gas Chromatography (GC) | Use capillary column gas chromatography with area normalization or internal standard method to determine the main component content and assess purity. |
| Moisture | Karl Fischer Titration | Determine moisture content by quantitatively reacting with Karl Fischer reagent through titration or coulometric methods. |
| Acid Value | Acid-Base Titration | Determine free acid in the sample using standard sodium hydroxide solution with phenolphthalein as an indicator, and calculate the acid value (mg KOH/g). |
| Color | Platinum-Cobalt Colorimetric Method | Determine the color grade by comparing the sample with standard platinum-cobalt color solutions (usually expressed in Hazen units). |
| Boiling Range/Boiling Point | Distillation or Gas Chromatography | Determine initial boiling point and dry point using a micro distillation apparatus, or estimate the boiling range using GC retention time. |
| Heavy Metals | Atomic Absorption Spectrometry (AAS) or ICP-MS | Determine residual amounts of heavy metals such as lead, arsenic, and mercury after sample digestion using atomic absorption spectroscopy or inductively coupled plasma mass spectrometry. |
| Organic Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Combine GC separation with MS identification for qualitative and quantitative analysis of possible by-products or degraded impurities (e.g., ethanol, monoethyl malate, etc.). |
| Refractive Index | Abbe Refractometer Method | Determine the refractive index of the sample at a specified temperature (usually 20°C), serving as an auxiliary indicator of purity. |
