Conclusions:
The vapour pressure of the test item was determined to be below the vapour pressure of hexachlorobenzene at 20 ºC (293K) and 25 ºC (298K):

Vapour pressure of the test item at 20 ºC: <1.5 x 10-3 Pa , < 1.1 x 10-5 mm Hg
Vapour pressure of the test item at 25ºC: < 6.9 x 10-3 Pa , < 5.2 x 10-5 mm Hg


Description of key information

The isothermal TGA effusion method was applied for the determination of the vapour pressure of the substance.

The vapour pressure of the test item was determined to be below the vapour pressure of hexachlorobenzene at 20 ºC (293K) and 25 ºC (298K):

Vapour pressure of the test item at 20 ºC:   <1.5 x 10 -3 Pa   ,  < 1.1 x 10-5 mm Hg

Vapour pressure of the test item at 25 ºC:  < 6.9 x 10 -3 Pa , < 5.2 x 10-5 mm Hg

Key value for chemical safety assessment

Vapour pressure:
0.007 Pa
at the temperature of:
25 °C
