Manufacturing Quality Control of 2,2-DIMETHYL-1,3-PROPANEDIAMINE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (DMAPA content) | Gas Chromatography (GC) with FID detection | Quantifies DMAPA peak area against calibrated standard using capillary column separation and flame ionization detection. |
| Water content | Karl Fischer titration | Measures water by coulometric or volumetric reaction of iodine with water in pyridine-methanol solvent system. |
| Color (APHA) | Visual comparison or spectrophotometric measurement at 430 nm | Compares sample color to platinum-cobalt standards or measures absorbance at 430 nm in a 10-mm cell. |
| Density at 20 C | Digital densitometer or pycnometer | Determines mass per unit volume using oscillating U-tube principle or calibrated glass pycnometer. |
| Refractive Index at 20 C | Refractometer | Measures bending of light through liquid sample at specified temperature using calibrated prism. |
| Acid value | Acid-base titration with NaOH and phenolphthalein | Neutralizes free acidic impurities using standardized sodium hydroxide solution and endpoint detection. |
| Amine value | Acid-base titration with HCl and methyl red indicator | Quantifies total basic nitrogen content via back-titration after acylation or direct titration. |
| Residue on evaporation | Gravimetric analysis | Evaporates known volume at 105 C and weighs non-volatile residue after drying to constant weight. |
| Heavy metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Measures absorbance of ground-state atoms in flame or graphite furnace after acid digestion and chelation. |
| Chloride content | Ion chromatography (IC) or potentiometric titration with AgNO3 | Separates and quantifies chloride anions via conductivity detection or determines by silver nitrate titration endpoint. |
| Aldehyde impurities (e.g., formaldehyde) | HPLC with UV detection after derivatization | Derivatizes aldehydes with DNPH, separates via reversed-phase column, and detects hydrazone derivatives at 360 nm. |
| Volatile impurities (e.g., methanol, DMF) | Gas Chromatography (GC) with headspace sampling | Analyzes low-boiling contaminants by equilibrium headspace gas injection into capillary GC column. |
