Industrial Applications of N,N,N'-TRIMETHYL-1,3-PROPANEDIAMINE
| Industry | Application | Process |
|---|---|---|
| Chemical Synthesis | Raw material for polyamide resins and curing agents | Undergoes condensation polymerization with dicarboxylic acids or dimeric acids to produce specialty polyamide resins, or serves as the amine component in epoxy resin curing systems. |
| Chemical Synthesis | Chain extender for polyurethane | Acts as a chain extender to link pre-polymer segments in the production of polyurethane (PU) synthetic leather, elastomers, and foam plastics. |
| Surfactants | Synthesis of zwitterionic surfactants | Incorporated as a hydrophilic moiety into long-chain fatty acids or fatty alcohols to produce surfactants with foaming and thickening properties. |
| Pharmaceuticals/Agrochemicals | Intermediate for pharmaceuticals and agrochemicals | Serves as a diamine structural unit containing a tertiary amine group in the synthesis of various active pharmaceutical ingredients and agrochemical compounds. |
| Coatings/Inks | Preparation of pigment dispersants | Grafted onto pigment particle surfaces via chemical reaction to provide steric hindrance, thereby improving dispersion stability in solvents or water. |
| Petroleum Industry | Corrosion inhibitor component | Used to synthesize adsorption-type corrosion inhibitors that form protective films on metal surfaces in acidic environments to prevent equipment corrosion. |
Manufacturing Quality Control of N,N,N'-TRIMETHYL-1,3-PROPANEDIAMINE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component using retention time and peak area calibration against certified reference standard. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Color | APHA Color Scale (Visual or Spectrophotometric) | Compares sample color to platinum-cobalt standard solutions using visual match or absorbance at 455 nm. |
| Density at 20 C | 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 C | Refractometry | Measures angle of light refraction at air-sample interface using calibrated prism and sodium D-line source. |
| Acid Number | Acid-Base Titration with NaOH | Neutralizes acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Amine Value | Acid-Base Titration with HCl | Quantifies total primary/secondary amine groups by back-titration after reaction with excess hydrochloric acid. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Measures non-volatile inorganic residue after controlled high-temperature combustion in muffle furnace. |
| Heavy Metals (as Pb) | ICP-OES | Detects trace metal elements by measuring characteristic atomic emission intensities after plasma atomization/excitation. |
| Chloride Content | Potentiometric Titration with AgNO3 | Determines chloride ions via precipitation titration monitored by silver ion-selective electrode. |
| Residual Solvents | Gas Chromatography (GC) with Headspace Sampling | Identifies and quantifies volatile organic impurities using equilibrium headspace gas analysis. |
| pH (10% aqueous solution) | pH Meter Measurement | Measures hydrogen ion activity in diluted aqueous solution using calibrated glass electrode system. |
