Manufacturing Quality Control of Diethyl ethoxymethylenemalonate
| Test Item | Common Test Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe sample color and physical state (e.g., colorless to pale yellow transparent liquid), assess clarity, and check for suspended particles or precipitates. |
| Purity | Gas Chromatography (GC) | Separation using a capillary column with FID detection; quantify main component content via peak area normalization or external standard method. |
| Moisture Content | Karl Fischer Titration | Quantitative reaction of iodine with sulfur dioxide in a pyridine/methanol system with water; determine trace moisture content by potentiometric titration. |
| Acid Value | Acid-Base Titration | Titrate free acids using phenolphthalein as indicator and standardized sodium hydroxide solution; calculate acid value (mg KOH/g). |
| Density | Densimeter / Oscillating Density Meter | Measure density directly at specified temperature (e.g., 20°C) using a hydrometer or digital density meter to evaluate product consistency. |
| Refractive Index | Abbe Refractometer Method | Determine refractive index at a specific temperature (e.g., 20°C); used as an auxiliary parameter for identification and purity control. |
| Boiling Point/Distillation Range | Distillation Method | Use a standard distillation setup to measure boiling point range or distillation temperature interval, assessing volatile impurities or compositional consistency. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Sample is sealed and heated; the headspace gas is injected into GC equipped with FID or MS detector to analyze residual organic solvents (e.g., ethanol, diethyl ether). |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) | After digestion, determine trace levels of heavy metal elements such as lead, arsenic, and mercury using flame or graphite furnace atomic absorption spectrometer. |
| Structural Confirmation | Fourier Transform Infrared Spectroscopy (FT-IR) or Nuclear Magnetic Resonance (NMR) | Verify molecular structure consistency by comparing characteristic functional group absorption peaks (IR) or ¹H/¹³C NMR spectra with reference spectra. |
