Applicant's summary and conclusion
- Conclusions:
- The isothermal thermogravimetric effusion method was chosen for the determination of the vapour pressure of Corsair Clear #12. The vapour pressure of the molten test substance extrapolated to 20°C (293K) ranged between 1.38 · 10-6 Pa (1.04 · 10-8 mm Hg) and 3.49 · 10-5 Pa (2.62 · 10-7 mm Hg).
