Description of key information
The vapour pressure of HFPO is 680.85 kPa (5106.8 mm Hg) at 25 °C.
Key value for chemical safety assessment
- Vapour pressure:
- 680.85 kPa
- at the temperature of:
- 25 °C
Additional information
The vapour pressure of HFPO was evaluated in two studies. In the key study, the vapour pressure was determined to be 680.85 kPa under a static method at 25°C. The static method is approved for this endpoint per OECD TG 104 but does not strictly follow the guideline nor was it conducted in accordance with GLP guidelines. This study is considered reliable with restrictions. In the supporting study, the vapour pressure was determined to be 649.9 kPa at 22.38 °C also by means of a static method not conducted in accordance with GLP guidelines. The supporting study is considered reliable with restrictions. The supporting study reported fewer vapour pressure data points near ambient temperature and does not provide an equation for vapour pressure extrapolation. Therefore, the key study result is considered the preferred value.
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.
