Environmental
Air pollutant (odor)
| Property | Value / Note |
|---|---|
| Physical state | Colorless gas with strong ammonia-like odor; compressed or dissolved in water/methanol. |
| Odour threshold | Very low — detectable at < 1 ppm. |
| Density (gas, 20 °C) | ≈ 1.9 kg/m³ |
| Reactivity | Base reacts exothermically with acids forming dimethylammonium salts; incompatible with oxidants. |
| Typical sources | Polymerization catalysts, surfactant manufacture, amination processes, degradation of amine-based compounds. |
*Values indicative — always verify via SDS and process-specific data before scrubber design.
