Results and discussion
Vapour pressure
- Temp.:
- 20 °C
- Vapour pressure:
- < 0 Pa
- Remarks on result:
- other: the vapour pressure of the test substance is < 1.33 x 10E-8 Pa = < 1.00 x 10E-10 mm Hg.
Any other information on results incl. tables
The weight loss of the test substance at 210°C, 220°C and 230°C was lower than the weight loss of benzo(ghi)perylene at the same temperatures. From this, it was concluded that the vapour pressure of the test substance is < 1.33 x 10-8 Pa = <1.00 x 10-10 mm Hg.
Applicant's summary and conclusion
- Conclusions:
- The vapour pressure of the test substance at 20°C (293K) was < 1.33 x 10E-8 Pa = < 1.00 x 10E-10 mm Hg.
