Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 test substance disodium persulfate was determined to decompose at ca. 453 K (= 180 °C) at 100.79 kPa before the boiling point was reached. Thus, no value for boiling temperature was determined.
Key value for chemical safety assessment
Additional information
The boiling point of the substances of the Persulfate Category was determined according to EU method A.2 applying photocell detection. Diammonium-, -potassium- and -sodium persulfate were found to decompose at ca. 120 °C (393 K), 100 °C (373K) and 180 °C (453 K) at atmospheric pressures of about 1000 hPa before the boiling point was reached. Thus, for all three substances, no value for boiling temperature was determined.
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.
