Results and discussion

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

Applicant's summary and conclusion

Conclusions:
The isothermal thermogravimetric effusion method was chosen for the determination of the vapour pressure of SX-1. 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.
