Any other information on results incl. tables
The weight loss of the test substance at 210°C, 220°C, 230°C and 240°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 Paz-E was lower than the vapour pressure of benzo(ghi)perylene.
Representative weight loss curves of the test substance and benzo(ghi)perylene are shown in Figures 10 and 11 (see attachment).
Applicant's summary and conclusion
- Conclusions:
- The vapour pressure of Paz-E at 20°C is < 1.3 x 10^-8 Pa
The vapour pressure of Paz-E at 25°C is < 1.6 x 10^-8 Pa
