Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
The experimentall determined reaction rate constant for the reaction of acetophenone with OH radicals in the gas-phase is reported to be 2.74 x 10E-12 cm³/molecule x s. Taking into account a OH radical concentration of 5 x 10E5 radicals/cm³ (24 h day) a tropospheric half-life t1/2=5.86 d can be calculated.
Key value for chemical safety assessment
- Half-life in air:
- 6 d
Additional information
The tropospheric half-life of acetophenone was determined using an experimentally determined reaction rate constant taken from a reliable source.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
