Applicant's summary and conclusion
- Conclusions:
- The vapour pressure of the Tetraethylammonium tetrafluoroborate at 20°C (293K) is < 0.000000013 Pa and at 25°C (298K) is: < 0.000000055 Pa.
- Executive summary:
The isothermal TGA effusion method was applied for the determination of the vapour pressure of Tetraethylammonium tetrafluoroborate. Weight loss rates were measured at 200°C, 210°C, 220°C and 230°C during the two experiments. In both experiments weight loss of the test item at 200°C, 210°C, 220°C and 230°C was lower than the weight loss of Benzo(ghi)perylene at the same temperatures. Based on this, it was safely concluded that the vapour pressure of the test item is lower than the vapour pressure of this reference substance. The vapour pressure of the Tetraethylammonium tetrafluoroborate at 20°C (293K) is < 0.000000013 Pa and at 25°C (298K) is: < 0.000000055 Pa.
