Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Hydrolysis is unlikely to be a significant pathway for the breakdown of Potassium Ferrite.
Key value for chemical safety assessment
Additional information
The hydrolisis of potassium ferrite was determined as part of a general study on the physico-chemical properties of the substance which was performed in compliance with GLP. The hydrolysis could not be determined according to the EC test guidelines as the substance is not soluble in water. Examination of the structure of Potassium Ferrite indicates that the likely form of the hydrolysis of the compound, should it occur, would be the conversion of the Ferrite to the also relatively insoluble iron oxide. Therefore, samples of Potassium Ferrite and the undissolved material from the end of a 144 hours water solubility test were analysed by Infra Red Spectroscopy (IR) to monitor for evidence of such a reaction occurring. lt was shown that a loss of peaks at around 1400 cm-1 from the post solubility test samples was due to the loss of potassium hydroxide. None of the peaks found could be attributed to the presence of iron (III) oxide. lt can thus be concluded that hydrolysis is unlikely to be a significant pathway for the breakdown of Potassium Ferrite.
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.
