Manufacturing Quality Control of Diallyl maleate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantitative determination based on peak area comparison against a certified reference standard using an appropriate capillary column. |
| Water Content | Karl Fischer Titration (Coulometric or Volumetric) | Electrochemical titration where iodine reacts stoichiometrically with water in a controlled anhydrous medium. |
| Acid Value | Acid-Base Titration (NaOH standard solution, phenolphthalein indicator) | Neutralization of free carboxylic acid groups by standardized sodium hydroxide; result expressed as mg KOH/g sample. |
| Refractive Index | Refractometry (at 20 °C) | Measurement of light bending angle through the liquid sample relative to air, correlated to purity and composition. |
| Density | Digital Density Meter (Oscillating U-tube principle) | Determination of mass per unit volume via precise measurement of oscillation frequency of a filled U-shaped tube. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement (430 nm) | Evaluation of yellowness intensity against platinum-cobalt standards or quantification of absorbance at specified wavelength. |
| Residue on Evaporation | Gravimetric Analysis (Hot Plate/Heating Oven) | Evaporation of a known sample mass under controlled temperature and pressure, followed by weighing of non-volatile residue. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) or ICP-OES after acid digestion | Quantification of trace metal impurities following microwave-assisted nitric acid digestion and instrumental detection. |
| Peroxide Value | Iodometric Titration | Oxidation of potassium iodide by peroxides to liberate iodine, titrated with standardized sodium thiosulfate. |
| Inhibitor Content (e.g., MEHQ) | High-Performance Liquid Chromatography (HPLC-UV) | Separation and quantification of phenolic inhibitors using reverse-phase column and UV detection at ~280 nm. |
| Distillation Range | Vacuum Distillation (ASTM D1078) | Measurement of initial boiling point and final boiling point under specified reduced pressure to assess volatility profile and presence of volatiles/residues. |
