Constant (H) ca Result: considerable volatility
Conditions: 20°C /calculated value
Soil/sediments, adsorption : log KOC ca. 2.2
Conditions: calculated value
Abiotic degradation
Air, indirect photo-oxidation : t ½ ca.25 year(s)
Conditions: sensitizer: OH radicals
Air, photolysis, ODP : = 0
Result: no effect on stratospheric ozone
Air, greenhouse effect, GWP : = 2900
Reference value for Co2 = 1 at 100 year
Biotic degradation
Aerobic, test : ready biodegradability/closed bottle
Degradation = 20 %, 28 day(s)
Result: non-readily biodegradable
