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).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
