Description of key information
Half-life for reaction with photochemically-produced hydroxyl radicals: estimated 11.8 hours.
Overall degradation rate constant with OH radicals= 2.83E-6 cm3/(molecule-day).
Key value for chemical safety assessment
- Half-life in air:
- 11.8 h
- Degradation rate constant with OH radicals:
- 0 cm³ molecule-1 d-1
Additional information
The stability of the test material in the atmosphere was calculated using the software AOPWIN (v1.92).
It is predicted that the test material will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals, with a half-life of 11.8 hours, at European test conditions.
The overall degradation rate constant with OH radicals was estimated to be 3.28E-11 cm3/molecule-sec, equivalent to 2.83E-6 cm3/molecule-day.
