Description of key information
The boiling point of HFPO is-28.45°C (244.70 K) by static method at 101.325 kPa (760 mm Hg).
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- -28.45 °C
Additional information
The boiling point of HFPO was evaluated in two studies. In the key study, the boiling point was determined to be -28.45 °C (244.70 K) under a static method at 101.325 kPa (760 mmHg). The static method is approved for measurement of vapour pressure (OECD 104) but is not mentioned in OECD 103 . Using the regression of the vapour pressures and temperatures, the temperature at which the vapour pressure equals the standard atmospheric pressure was found. The study was not conducted in accordance with GLP guidelines. This study is considered reliable with restrictions. In the supporting study, the boiling point was determined to be -27.40°C (245.75 K). The report specifies neither the methods used to obtain this temperature nor the pressure at which the measurements were obtained. The reliability of the supporting study could not be assessed, yet it supports the key study results.
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.
