Results and discussion

Vapour pressure
Temp.:
20 °C
Vapour pressure:
< 0 Pa
Remarks on result:
other: Estimated vapour pressure value.

Any other information on results incl. tables

The weight loss of the test substance at 230 deg C was lower
than that of benzo(ghi)perylene (with a vapour pressure of
1.47E-8 at 20 deg C) at the same temperature: the vapour
pressure of the test substance is < 1.47E-8 Pa (< 1.10E-10
mm Hg).
