- Executive summary:
A study was conducted according to OECD TG 104, Regulation (EC) No 440/2008 method A.4 and OPPTS 830.7950 to determine the vapour pressure of the test item. The vapour pressure of the test item was determined using the effusion method (weight loss). The vapour pressure was determined within the temperature range of 125.9 to 150.9 °C. The test item showed no proper linear correlation of the vapour pressure and the inverse temperature 1/T. Thus, the vapour pressures for the temperatures 20, 25 and 50 °C could only be estimated. On the basis of the maximum measured vapour pressure of 5.19 x 10-1 Pa, determined for 150.9 °C a vapour pressure of <0.5 Pa was estimated for 20, 25 and 50 °C.
Reference
The vapour pressure was measured in the temperature range of 125.9 to 150.9 °C.

Due to the fact that the test item showed no proper linear correlation of the vapour pressure and the inverse temperature 1/T, the Antoine constants cannot be evaluated in the measured temperature range. Due to this result, the vapour pressure for the temperatures 20, 25 and 50 °C was estimated on the basis of the maximum measured vapour pressure of 5.19 x 10-1 Pa at a temperature of 150.9 °C to be <0.5 Pa.
Description of key information
The vapour pressure of the test item was estimated to be <0.5 Pa at 20 °C.
Key value for chemical safety assessment
- Vapour pressure:
- 0.5 Pa
- at the temperature of:
- 20 °C
