Description of key information

With an experimentally determined vapur pressure of 0.0084 Pa at 20 °C, and 0.0332 Pa at 50 °C the substance is of very low vapour presssure. The determination was carried out according to OECD 104 (Knudsen effusion method).

Key value for chemical safety assessment

Vapour pressure:
0.008 Pa
at the temperature of:
20 °C

Additional information

Using the Knudsen effusion method (mass loss), according to the guidelines OECD 104 / EU A.4, the determined vapour pressure of the substance was 0.0084 Pa at 20 °C, 0.0107 Pa at 25 °C, and 0.0332 Pa at 50 °C.
