Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Irradiation of crotonaldehyde vapour in the presence of oxygen at a wavelength range of 238 - 366 nm (ultraviolet range) leads to a oxidation to crotonic acid. The quantum yield of the oxidation process increased with decreasing wave length.
In an acidic environment it is reversibly hydrated to aldol. The illumination of an aqueous solution of crotonaldehyde with unfiltered light on a mercury arc resulted in an only slight degradation of the substance and the formation of insoluble condensation products within a few minutes.
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.
