Manufacturing Quality Control of N-Methylcaprolactam
| 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 a polar capillary column. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water in the sample. |
| Acidity (as H2SO4) | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 430 nm | Measurement of yellowness intensity by comparing sample absorbance at 430 nm to APHA platinum-cobalt standards. |
| Density at 20 degC | Digital Density Meter (Oscillating U-tube principle) | Determination of mass per unit volume based on resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Refractive Index at 20 degC | Abbe Refractometer | Measurement of light bending angle at air-sample interface to determine refractive index as a function of molecular composition. |
| Residue on Evaporation | Gravimetric Analysis (Hot Plate Evaporation) | Evaporation of a measured sample volume to dryness under controlled conditions, followed by weighing of non-volatile residue. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) after acid digestion | Quantification of total heavy metals via flame or graphite furnace AAS after microwave-assisted nitric acid digestion. |
| Iron (Fe) Content | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Multi-element detection based on characteristic atomic emission lines following acid dissolution and nebulization. |
| Aldehyde Impurities (e.g., Hexanal) | Gas Chromatography-Mass Spectrometry (GC-MS) | Separation and identification of volatile aldehyde impurities using retention time and mass spectral matching. |
| Residual Solvents (e.g., Toluene, Heptane) | Headspace Gas Chromatography (HS-GC) with FID | Quantification of volatile organic solvents by equilibrium partitioning into headspace followed by GC separation. |
| Non-Volatile Matter | Gravimetric Analysis (Rotary Evaporator + Drying) | Evaporation of solvent under reduced pressure, drying at 105 degC, and weighing of residual solids. |
