Description of key information
244.3 °C at 1013.25 hPa
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 244.3 °C
Additional information
A study was conducted to determine the boiling point of the substance. Therefore, using the dynamic method a vapour pressure curve was recorded. At 1000.570 hPa a temperature of 243.99 °C was measured. The parameter of the Antoine equation were determined and the boiling point at 1013.3 hPa was calculated to be 244.3 °C. In addition a study was conducted to determine the vapour pressure of the substance at different temperatures. At 247.1 °C the vapour pressure of the substance was determined to be 1013.25 hPa. Furthermore Mandel 1954 (as cited in Registry, 2014) reports the boiling point to be at 244-246 °C. All reported values are in the same range and therefore regarded as reliable. A boiling point of 244.3 °C was chosen as key value for chemical safety assessment as it was from the study with the most pure substance.
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.
