Thermal Stability
The DSC run PN18027 is shown in Figure 1 (kindly refer the attached background material section of the IUCLID). In the temperature range of 30 - 50 °C a first endothermic effect can be observed. A second endothermic effect was detected in the temperature range of 170 - 210 °C. The test was terminated at 300 °C.
Effusion method: Knudsen cell
The vapour pressure was measured in the temperature range of 100 to 125 °C. The measured vapour pressure values together with the measured temperatures are listed in below table:

Figure 2 shows the vapour pressure as a function of the inverse temperature 1/T (kindly refer the attached background material section of the IUCLID). Segment No. 1 was not considered for the linear regression since water was evaporated from the test substance at the beginning of the examination.
The vapour pressure of the test substance was calculated by 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 1.4E-7 Pa, 3.5E-7 Pa and 2.0E-5 Pa at 20°C, 25°C and 50°C respectively.
Description of key information
The vapour pressure of the test substance was determined using the Knudsen cell Effusion method according to OECD Guideline 104 and EU Method A.4 (Hartmann, 2019).
Key value for chemical safety assessment
- Vapour pressure:
- 0 Pa
- at the temperature of:
- 20 °C
Additional information
Vapour pressure: 1.4E-7 Pa, 3.5E-7 Pa and 2.0E-5 Pa at 20°C, 25°C and 50°C respectively.
