Description of key information
The vapour pressure of the test material was determined to be less than 0.131 Pa, OECD 104, EU Method A.4, Henke (2013)
Key value for chemical safety assessment
- Vapour pressure:
- 0.131 Pa
- at the temperature of:
- 75 °C
Additional information
The vapour pressure of the test material was investigated in a GLP study which was conducted in accordance with the standardised guidelines OECD 104 and EU Method A.4, using the effusion method.
Vapour pressure was examined at nine different temperatures (30, 45, 60, 75, 90, 105, 120, 135 and 150 °C). No evaluation on the basis of the measured weight losses was possible. Furthermore, no mean molecular mass could be stated.
The vapour pressure of the single measurements were therefore calculated on the basis of the minimum and maximum possible molecular masses of the test material (617 and 914 g/mol, respectively) and the maximum vapour pressure of all single measurements was stated as limit value for the vapour pressure of the test material.
The vapour pressure of the test material was determined to be less than 0.131 Pa. This maximum value was calculated from the weight loss of cell 4 at 75 °C using a molecular mass of 617 g/mol.
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.
