Manufacturing Quality Control of 2-Methyleneglutaronitrile
| 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 using a polar capillary column. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in anhydrous methanol/pyridine medium. |
| Acid Number | Acid-Base Titration with NaOH | Neutralization of acidic impurities (e.g., HCN, carboxylic acids) using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 430 nm | Comparison of sample color to APHA platinum-cobalt standards or measurement of absorbance at 430 nm in a 10-mm cell. |
| Residue on Evaporation | Gravimetric Analysis | Evaporation of a weighed sample under controlled temperature and pressure, followed by weighing of non-volatile residue. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals after acid digestion by measuring absorbance of ground-state atoms at element-specific wavelengths. |
| Cyanide (Free CN-) | Spectrophotometric Detection after Pyridine-Barbituric Acid Reaction | Formation of a red chromophore upon reaction of free cyanide with chloramine-T and pyridine-barbituric acid, measured at 578 nm. |
| 2-Methylglutaronitrile (Isomer Impurity) | Gas Chromatography (GC) with FID detection | Separation and quantification of structural isomer using a high-resolution capillary column and external calibration. |
| Hexahydrophthalimide (Cyclization By-product) | High-Performance Liquid Chromatography (HPLC) with UV detection | Reversed-phase separation followed by UV absorbance detection at 210 nm for cyclic imide quantification. |
| Residual Solvents (e.g., CH2Cl2, MeOH) | Gas Chromatography (GC) with Headspace Sampling | Headspace equilibration followed by GC-FID analysis using a DB-624 column for volatile organic solvent quantification. |
| Density at 20 degC | Digital Density Meter Measurement | Oscillating U-tube principle where sample density is derived from the resonant frequency of a vibrating filled tube. |
| Refractive Index at 20 degC | Abbe Refractometer Measurement | Determination of refractive index based on critical angle of total internal reflection at the prism-sample interface. |
