Description of key information
Additional information
There are two reliable experimental studies for photo degradation in air. The overall loss rate of acetone including photo dissociation and loss by reaction with OH radicals and the corresponding lifetimes were calculated for January, Equinox and July at 40 degree northern latitude. Lifetimes were 18.6 - 114.4 days. This is in accordance with the findings of the second study. The photo dissociation lifetime for 40°solar angle is 1/kdissoc = 14.8 days. Based on the weight of evidence and on the molecular structure acetone is resistant to hydrolysis. In water acetone may form the ketal by hydration, however ketal formation is reversible.
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.
