Vapour pressure
- Temp.:
- 20 °C
- Vapour pressure:
- < 0 Pa
- Remarks on result:
- other: The vapour pressure of the test substance at 20°C (293K) was < 1.33 x 10-8 Pa; i.e. < 1.00 x 10-10 mm Hg at 20°C by isothermal thermogravimetry
Applicant's summary and conclusion
- Conclusions:
- The isothermal thermogravimetric effusion method was chosen for the determination of the vapour pressure of ASA404 C7. The vapour pressure of the test substance at 20°C (293K) was < 1.33 x 10-8 Pa, i.e. = < 1.00 x 10-10 mm Hg.
