Headspace vapour concentrations of Tbodiol as found after an equilibration time of 72, 96, 120 and 144 hours are exposed:
| Equilibration time [h] | Headspace concentration [µg/l] | Headspace concentration [g/m^3] |
| 72 | 11.2 | 0.0112 |
| 96 | 11.1 | 0.0111 |
| 120 | 11.2 | 0.0112 |
| 144 | 10.9 | 0.0109 |
Applicant's summary and conclusion
- Conclusions:
- The vapour pressure of Tbodiol at 20°C was calculated from the average headspace concentration.
The result was 0.14 Pa.
Therefore:
Vapour pressure of Tbodiol: 0.14 Pa at 20°C - Executive summary:
The vapour pressure of the test material Tbodiol has been determined to be 0.14 Pa at 20°C using the Gas saturation method.
Therefore:
Vapour pressure of Tbodiol: 0.14 Pa at 20°C;
