| Property | Value / Note |
|---|---|
| Chemical identity | Secondary amine, (i-Pr)₂NH; clear, strongly odorous liquid. |
| Molar mass | ≈ 101.2 g/mol |
| Reactivity | Strong base; rapid salt formation with mineral acids (e.g., sulfate/chloride). Incompatible with strong oxidizers; may stress-crack some plastics/coatings. |
| Behaviour in gas streams | Moderately volatile; capture efficiency is high when protonated in acidic liquor. Risk of salt mist/slip at low pH and high gas velocity. |
| Best analytical detection | FTIR (inline) — continuous, selective detection via N–H/C–N bands; ideal for process/leak monitoring and scrubber outlet control without reagents. |
