Description of key information

Using the isothermal thermogravimetric effusion method, the vapour pressure of the substance at 20°C (293K) was 2.30 x 10-6 Pa = 1.73 x 10-8 mm Hg. 

Key value for chemical safety assessment

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

Additional information

Estimation of the vapour pressure of the liquefied substance at 61°C (334K) and 80°C (353K) was performed using the data from the isothermal thermogravimetric effusion method.

At 61°C (334K) the vapour pressure is 5.71 x 10 -4 Pa.

At 80°C (353K) the vapour pressure is 4.76 x 10 -3 Pa.
