Results and discussion

Vapour pressure
Temp.:
20 °C
Vapour pressure:
< 0 Pa

Any other information on results incl. tables

No significant weight loss of the test substance was observed in the temperature range of 40°C – 80°C (i.e. below its melting temperature).The weight loss of the test substance was lower than the weight loss ofbenzo(ghi)perylene. From this, it was concluded that the vapour pressure of the test substance is < 1.33 x 10-8Pa = <1.00 x 10-10mm Hg.

Applicant's summary and conclusion

Conclusions:
The isothermal thermogravimetric effusion method was chosen for the determination of the vapour pressure of the test substance. The vapour pressure of the test substance at 20°C (293K) was < 1.33E-8 Pa = < 1.00E-10 mm Hg.
