Any other information on results incl. tables
The weight loss of the test substance at 170°C, 180°C, 190°C and 200°C was lower than the weight loss of chrysene at the same temperatures. From this, it was concluded that the vapour pressure of the test substance is < 8.40 x 10 -7 Pa = <6.30 x 10 -9 mm Hg.
Applicant's summary and conclusion
- Conclusions:
- The isothermal thermogravimetric effusion method was chosen for the determination of the vapour pressure of the substance. The vapour pressure of the test substance at 20°C (293K) was < 8.40 x 10-7 Pa = < 6.30 x 10-9 mm Hg.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
