- Executive summary:
The vapour pressure was determined using by the Effusion Method: Knudsen Cell in EU Method A.4 and OECD TG 104. The vapour pressure of the test substance was calculated by interpolation and extrapolation of the measured vapour pressure curve for the temperatures 20, 25 and 50 °C. The vapour pressure of the test substance was determined to be at test substance was determined to be at 20°C: 0.12 Pa and at 25°C: 0.18 Pa respectively.
Reference
Thermal Stability
The DSC run in a closed glass crucible under an inert atmosphere was determined. In the temperature range of 190 – 300 °C an endothermic effect can be observed, no exothermic decomposition reaction were observed up to the maximum measured temperature of 300 °C.
Effusion method: Knudsen cell
The vapour pressure was measured in the temperature range of 10 to 40 °C. The measured vapour pressure values together with the measured temperatures are listed.
Table 1: Results of the Effusion method
No. | Temperature / °C | Vapour pressure / Pa |
1 | 10 | 0.05 |
2 | 15 | 0.08 |
3 | 20 | 0.17 |
4 | 25 | 0.19 |
5 | 30 | 0.24 |
6 | 35 | 0.34 |
7 | 40 | 0.51 |
From the measured data points on the vapour pressure curve the measured constants A and B of the Antoine equation were determined as: A = 8.7012; B = -2819.27 and C = 273.15. The vapour pressure of the test item was calculated by extrapolation of the measured vapour pressure curve for the temperatures 20, 25 and 50 °C.
