Manufacturing Quality Control of N,N'-DIMETHYL-1,4-BUTANEDIAMINE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies main component peak area relative to calibration curve using internal or external standard. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between iodine, sulfur dioxide, and water in methanol-based reagent. |
| Color | Visual Comparison or Spectrophotometry (APHA scale) | Compares sample color against platinum-cobalt standard solutions or measures absorbance at 455 nm. |
| Acid Value | Acid-Base Titration with NaOH | Determines free acidic impurities by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Amine Value | Acid-Base Back Titration | Measures total basic nitrogen content by reacting excess standardized HCl, then back-titrating unreacted acid with NaOH. |
| Residue on Ignition | Gravimetric Analysis | Weighs non-volatile inorganic residue remaining after high-temperature combustion in a muffle furnace. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies trace metal impurities by measuring absorption of specific wavelength light by ground-state atoms in flame or graphite furnace. |
| Chloride Content | Potentiometric Titration with AgNO3 | Detects chloride ions by titration with silver nitrate using silver indicator electrode and reference electrode. |
| Density | Digital Density Meter | Determines mass per unit volume at specified temperature using oscillating U-tube principle. |
| Refractive Index | Refractometry | Measures bending of light as it passes through liquid sample at controlled temperature to infer purity and concentration. |
| Volatile Impurities | Headspace Gas Chromatography (HS-GC) | Separates and quantifies low-boiling organic impurities by analyzing vapor phase above heated sample. |
| Appearance | Visual Inspection | Assesses physical state, clarity, and presence of suspended particles or phase separation under controlled lighting conditions. |
