- The vapour pressures of the test item were determined to be 1.9*10^-3 Pa (20 °C), 3.8*10^-3 Pa (25 °C) and 8.7*10^-2 Pa (50 °C).
- Executive summary:
A study was performed according to OECD TG 104 in order to determine the vapour pressure of the test item by using the effusion method (vapour pressure balance). The vapour pressure was measured at various temperatures between 18 and 74 °C. The vapour pressures of the test item at 20, 25 and 50 °C were extrapolated by using the Antoine constants. The vapour pressures of the test item were determined to be 1.9*10^-3 Pa (20 °C), 3.8*10^-3 Pa (25 °C) and 8.7*10^-2 Pa (50 °C).
Reference
Thermal stability
The DSC-measurement in a closed glass crucible showed two endothermic effects (melting) in the temperature range of 50 – 60 °C and 80 – 100 °C and no exothermal effect until 400 °C.
Vapour pressure balance (effusion method)
The vapour pressure was measured in the temperature range of 18 °C to 74 °C. Above 36 °C a vapour pressure could be measured. The measured vapour pressures at the corresponding temperatures are listed in the following table:
Temperature / °C | Vapour pressure / hPa |
36.6 | 1.6*10^-4 |
37.9 | 2.3*10^-4 |
38.2 | 2.4*10^-4 |
38.4 | 1.5*10^-4 |
42.6 | 4.0*10^-4 |
47.7 | 8.1*10^-4 |
51.7 | 1.1*10^-3 |
57.7 | 2.1*10^-3 |
64.4 | 3.9*10^-3 |
70.6 | 5.2*10^-3 |
73.7 | 5.8*10^-3 |
At the beginning of the measurement the test item is solid up to a temperature of approx. 65 °C. Above 65 °C the test item started to melt. Due to this the regression according to the Antoine equation was performed only for the vapour pressure of the solid product.
The values for 20, 25 and 50 °C are calculated, using the Antoine constants A, B and C. Following constants were determined: A=13.10230, B=-5223.54, C=273.15.
Description of key information
The vapour pressures of the test item were determined to be 1.9*10^-3 Pa (20 °C), 3.8*10^-3 Pa (25 °C) and 8.7*10^-2 Pa (50 °C).
Key value for chemical safety assessment
- Vapour pressure:
- 0.004 Pa
