Description of key information

Vapour pressure = 2.6 x 10-2 at 20 ºC, 4.3 x 10-2 at 25 ºC and 4.2 x 10-1 at 50 ºC, OECD 104, EU Method A.4, EPA OPPTS 830.7950, Möller 2012a

Key value for chemical safety assessment

Vapour pressure:

Additional information

The vapour pressure of the test material was determined in a key study (Möller, 2012a) performed in accordance with the standardised guidelines OECD 104, EU Method A.4 and EPA OPPTS 830.7950 using the effusion method.

The vapour pressure of the test material was determined in accordance with the standardised guidelines OECD 104, EU Method A.4 and EPA OPPTS 830.7950 using the effusion method. Under the conditions of the test, the vapour pressure of the test material was determined to be 2.6 x 10-2 Pa at 20 ºC, 4.3 x 10-2 Pa at 25 ºC and 4.2 x 10-1 Pa at 50 ºC. These values are considered to be artifically high as a result of the moisture content of the test substance. The true vapour pressure of the substance to be registered is considered to be much lower than this.
