Manufacturing Quality Control of DIMETHYL UNDECANEDIOATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard under optimized chromatographic conditions. |
| Acid Value | Acid-Base Titration with KOH in ethanol | Neutralization of free carboxylic acid groups using standardized potassium hydroxide solution, with phenolphthalein endpoint detection. |
| Water Content | Karl Fischer Coulometric Titration | Electrochemical quantification of water via iodine generation and stoichiometric reaction with water in anhydrous methanol-based reagent. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 455 nm | Comparison of sample solution color intensity against APHA platinum-cobalt standards or absorbance measurement at specified wavelength. |
| Residue on Ignition | Gravimetric Analysis after High-Temperature Ashing | Determination of non-volatile inorganic impurities by weighing residue remaining after combustion at 700-800 C in a muffle furnace. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) after wet digestion | Quantification of total heavy metals following acid digestion and measurement of absorbance at element-specific wavelengths. |
| Chloride Content | Potentiometric Titration with AgNO3 | Precipitation titration where chloride ions react with silver nitrate, detected by silver indicator electrode potential change. |
| Refractive Index | Refractometry at 20 C | Measurement of light bending angle through liquid sample relative to air, correlated to molecular composition and purity. |
| Density at 20 C | Digital Density Meter or Pycnometer | Mass per unit volume determined by oscillating U-tube principle or calibrated glass pycnometer at controlled temperature. |
| Flash Point | Cleveland Open Cup (COC) Method | Minimum temperature at which vapors above the heated sample ignite momentarily when exposed to flame under standardized conditions. |
| Melting Point | Capillary Melting Point Apparatus | Temperature range at which solid-to-liquid phase transition occurs, observed visually or automatically via thermal analysis. |
| Residual Solvents (e.g., methanol) | Headspace Gas Chromatography (HS-GC) with FID | Quantitative analysis of volatile organic solvents by equilibrium partitioning into headspace followed by GC separation and detection. |
