Description of key information

Vapour Pressure (OECD 104, EU Method A.4.). The vapor pressure is is 0.164 at 20 °C and 0.323 at 25 °C.

Key value for chemical safety assessment

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

Additional information

The vapour pressure of Di-n-butylfumaratewas determined following EU A.4 by the effusion method (weight loss).

For the test item Di-n-butylfumarate, the following vapour pressures at 20 °C and 25 °C were calculated from the regression equation:

Vapour pressure at 20 °C:        0.164 Pa

Vapour pressure at 25 °C:        0.323 Pa
