Description of key information
A half-life t1/2=4.5 d was calculated for the photodegradation of benzophenone in air by reaction with OH radicals .
Key value for chemical safety assessment
- Half-life in air:
- 4.5 d
Additional information
The photodegradation of benzophenone in air by reaction with OH radicals was calculated using EPIWIN v4.0, AOPWIN v1.92. Based on the reaction rate constant k(OH)=3.5549 x 10E-12 cm³/molecule x sec and assuming a tropospheric OH radical concentration of 5 x 10E5 radicals/cm³ a half-life t1/2=4.5 d is obtained.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
