Description of key information
In the atmosphere etherdiamines is likely to be degraded by reaction with hydroxyl radicals. Degradation rates for some components were calculated with the Atmospheric Oxidation Programme based on structure activity relationships developed by Atkinson (1987). With a concentration of 500,000 OH-radicals/cm3, degradation half-lives of 2.57 h and 1.97 h for resp the free amine and diacetate were calculated. For the exposure calculations, a mean value of 2.27 may be used. Because there are no important releases into the atmosphere and volatilisation is expected to be negligible, this removal mechanism is thought to be of low relevance.
Key value for chemical safety assessment
- Half-life in air:
- 2.27 h
Additional information
Because the low vapour pressure of 3.1 mPa, there are no important releases into the atmosphere and volatilisation is expected to be negligible, this removal mechanism is thought to be of low relevance.
