Description of key information

The QSAR calculated rate constant for the OH sensitized photodegradation of 1,5,9-cyclododecatriene is approximately 1.76E-10 cm3/(molecule * s). At 500,000 OH radicals / cm3 (approximate 24-hour mean in central Europe), this corresponds to a half-life of 2.2 hours.
The QSAR calculated rate constant for the ozone sensitized photodegradation of 1,5,9-cyclododecatriene is approximately 6.0E-16 cm3/(molecule * s). At 7.0E+11 O3 molecules / cm3, this corresponds to a half-life of 0.5 hours.
The combined half-life for OH radical and O3 molecule reactions is approximately 23 minutes.
