Key result
Test no.:
#1
Temp.:
20 °C
Vapour pressure:
0.014 Pa
Conclusions:
Under the test conditions, the vapour pressure of the test substance at 20°C was determined to be 0.0136 Pa (1.36E-2 Pa).
Executive summary:

A study was performed to determine the vapour pressure of the test substance according to the isothermal thermogravimetry effusion method.

Under the test conditions, the vapour pressure of the test substance at 20°C was determined to be 1.36E-2 Pa (1.02E-4 mm Hg).

Description of key information

Vapour pressure was determined with the isothermal thermogravimetry effusion method (OECD Guideline 104) (Oudhoff, 2010).
