- Conclusions:
- The vapour pressure of the test item at 20°C is 301.1 mbar +/- 2.5 mbar (301.1 hPa)
The vapour pressure of the test item at 25°C is 370.9 mbar +/- 2.5 mbar (370.9 hPa) - Executive summary:
The vapour pressure of the test item has been determined with the static method according to recognized guidelines (EU Method A.4 and OECD Guideline 104).
The vapour pressure of the test item at 20°C is 301.1 mbar +/- 2.5 mbar (301.1 hPa)
The vapour pressure of the test item at 25°C is 370.9 mbar +/- 2.5 mbar (370.9 hPa)
Reference
The measured vapour pressure were used to regress the coefficient of Antoine's law. They enable to claculate the vapour pressure of the test item at any given temperature
Description of key information
One reliable study (Klimisch 1) is available.
The vapour pressure of the test item has been determined with the static method according to recognized guidelines (EU Method A.4 and OECD Guideline 104). The test was GLP compliant and no deviation from the guideline has been observed during the test.
The vapour pressure of the test item at 20°C is 301.1 mbar +/- 2.5 mbar (301.1 hPa)
The vapour pressure of the test item at 25°C is 370.9 mbar +/- 2.5 mbar (370.9 hPa)
Key value for chemical safety assessment
- Vapour pressure:
- 301.1 hPa
- at the temperature of:
- 20 °C
Additional information
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.
