Manufacturing Quality Control of N-PROPYL-1,3-PROPANEDIAMINE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component by retention time and peak area comparison against certified reference standard. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between iodine, sulfur dioxide, and water in methanol/pyridine medium. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 430 nm | Evaluates yellowness by comparing sample absorbance at 430 nm to platinum-cobalt standard solutions. |
| Density at 20 degC | Digital Density Meter (Oscillating U-tube) | Determines density from resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Refractive Index at 20 degC | Abbemat Refractometer | Measures refractive index based on critical angle of total internal reflection at prism-sample interface. |
| Acid Value | Acid-Base Titration with NaOH and phenolphthalein indicator | Quantifies acidic impurities by titration with standardized sodium hydroxide solution to phenolphthalein endpoint. |
| Amine Value | Acid-Base Back Titration with HCl and NaOH | Determines total basic nitrogen content by reacting excess HCl with amine groups, then back-titrating unreacted acid. |
| Residue on Ignition | Gravimetric Analysis after High-Temperature Ashing | Measures non-volatile inorganic residue remaining after combustion at 750 degC in a muffle furnace. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) after wet digestion | Quantifies trace metals by measuring atomic absorption of characteristic wavelength light after acid digestion. |
| Chloride Content | Potentiometric Titration with AgNO3 | Detects chloride ions by monitoring potential change during silver nitrate titration using silver/silver chloride electrode. |
| Non-Volatile Residue | Gravimetric Analysis after Evaporation at 105 degC | Measures residue left after evaporating known volume under controlled temperature and weighing dried residue. |
| Gas Impurities (NH3, low-MW amines) | Headspace GC-MS | Identifies and quantifies volatile impurities by gas-phase extraction followed by mass spectral detection and library matching. |
