The vapour pressure of the sample was tested according to EU Method A.4 and OECD Guideline 104 in a non-GLP study with the effusion method.
The following vapour pressure values for the test item were extrapolated from the experimental data:
20 °C: 0.00013 hPa
25 °C: 0.00026 hPa
50 °C: 0.0056 hPa
Reference
The vapour pressure was measured in the temperature range of 30 °C to 60 °C. The measured vapour pressures at the corresponding temperatures are listed in the following table:
| Temperature [°C] | Vapour pressure [hPa] |
| 30 | 5.0 x 10-4 |
| 35 | 8.7 x 10-4 |
| 40 | 1.8 x 10 -3 |
| 45 | 3.5 x 10 -3 |
| 50 | 5.7 x 10 -3 |
| 55 | 9.5 x 10-3 |
| 60 | 1.60 x 10 -2 |
The figure (attached as background material) gives the vapour pressure (logarithmic scale) as a function of the inverse temperature (1/T, T in Kelvin). Only for better readability the temperature is also reported in a centigrade scale. The values for 20, 25 and 50 °C are calculated, using the Antoine constants A, B and C as shown there.
| T [°C] | p [hPa] | p [Pa] |
| 20 | 1.3 x 10-4 | 1.3 x 10 -2 |
| 25 | 2.6 x 10-4 | 2.6 x 10 -2 |
| 50 | 5.6 x 10 -3 | 5.6 x 10-1 |
Description of key information
The vapour pressure of the sample was tested according to EU Method A.4 and OECD Guideline 104 in a non-GLP study with the effusion method.
