Results and discussion

Vapour pressure
Temp.:
20 °C
Vapour pressure:
< 0 hPa
Remarks on result:
other: < 1.1E-05 mg Hg

Any other information on results incl. tables

The weight loss of the test substance at 110 °C, 120 °C, 130 °C and 140 °C was lower than the weight loss of hexachlorobenzene at the same temperatures (see weight loss curves below). From this, it was concluded that the vapour pressure of the test substance is < 1.47E-05 hPa (< 1.1E-05 mm Hg).

Applicant's summary and conclusion

Conclusions:
The isothermal thermogravimetric effusion method was chosen for the determination of the vapour pressure. The vapour pressure of the test substance at 20 °C (293K) was < 1.47E-05 hPa (< 1.1E-05 mm Hg).
