Description of key information
The boiling point of anhydrous N,N-diethylhydroxylamine is 134°C at 1013hPa
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 134 °C
Additional information
Several studies are available on the boiling point of N,N-diethylhydroxylamine (100% and 85%). Both studies on anhydrous N,N-diethylhydroxylamine give a boiling point around 134°C. Study on N,N-diethylhydroxylamine 85% gives a boiling point at 96°C.
Based on those results and on the measured flash point, N,N-diethylhydroxylamine 100% and N,N-diethylhydroxylamine 85% in water
should be classified Flammable liquid Category 2 H226 Flammable liquid and vapour according to Regulation (EC) No 1272/2008Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
