Thermal Stability
The DSC measurement in a closed glass crucible showed an endothermic effect in the temperature range 200 -300°C directly followed by an exothermal decomposition in the temperature range 230 -300°C.
Vapour Pressure Balance (Effusion Method)
The vapour pressure was measured in the temperature range of 16°C to 129°C. No signal was observed up to a temperature of 56°C. Above 62°C a vapour pressure could be measured. The measured vapour pressure at the corresponding temperature are listed in the following table:
| Temperature/°C | Vapour pressure/ hPa |
| 62.4 | 1.1exp-05 |
| 67.9 | 1.7exp-05 |
| 68.1 | 1.7exp-05 |
| 74.7 | 5.2exp-05 |
| 75.0 | 6.9exp-05 |
| 81.4 | 1.2exp-04 |
| 87.1 | 2.3exp-04 |
| 94.6 | 5.7exp-04 |
| 100.5 | 9.3exp-04 |
| 106.5 | 9.3exp-04 |
| 115.0 | 3.3exp-03 |
| 121.3 | 6.0exp-03 |

Applicant's summary and conclusion
- Conclusions:
- A vapour pressure of 5.6 exp-06 Pa at 25 °C was calculated by extrapolation.
