Description of key information

Phototransformation in air

After evaporation or exposure to the air, the substance will be rapidly degraded by photochemical processes.


According to structural properties, hydrolysis is not expected. Moreover, the substance is readily biodegradable.


Dibutylamine is readily biodegradable (according to OECD criteria).


Significant accumulation in organism is not to be expected.


The substance might adsorb to the solid soil phase under environmentally relevant conditions. However, the substance is readily biodegradable.

Henry´s Law constant

From the water surface, the substance will not evaporate into the atmosphere under environmentally relevant conditions.

Distribution modelling

The uncharged substance preferably distributes into the compartments air (72.6%) and water (26.9%). However, the data refer to the uncharged molecule (calculated pKa value: 11). The substance is supposed to be charged under environmentally relevant conditions. Therefore the distribution into water may be underestimated.
