Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Transition / decomposition:
no
Remarks:
No degradation of the test item was observed. No significative losses of mass were recorded during the different assays.

The mass of sample weighed for each assay was reported in the table below. The sample was placed in a Knudsen effusion cell. Then the cell was placed in the apparatus.

 Assay N°  T°C  Mass of the test item (mg)  Knudsen effusion cell aperture size (µm)  Taken into account or not
 1  85  4.87 279.9  Yes 
 2  100  4.87 279.9  Yes
 3  115 4.87 279.9  Yes
4   130  4.87  279.9 Yes 

No degradation of the test item was observed. No significative losses of mass were recorded during the different assays. The limit of detection of the apparatus is 10-3 Pa and the losses of mass recorded correponded to vapour pressures lower than 10-3 Pa and were not considered as reliable.

As a consequence, we can consider that the vapour pressure of the test item was lower than 10-3 Pa at 130 °C (temperature at which no significative loss of mass was observed and thus at which the test item was not decomposed). By extrapolation, the vapour pressure of the test item was considered to be largely lower than 10-3 Pa at 20 °C.

Conclusions:
The vapour pressure of the test item was lower than 10-3 Pa at 130 °C and thus the vapour pressure of the test item was considered to be largely lower than 10-3 Pa at 20 °C.

Description of key information

The vapour pressure of the test item was considered to be largely lower than 10-3 Pa at 20 °C according to experimental test carried out under OECD guideline 104 (effusion method: vapour pressure balance).

Key value for chemical safety assessment

Additional information

The vapour pressure of the test item was lower than 10-3 Pa at 130 °C and thus the vapour pressure of the test item was considered to be largely lower than 10-3 Pa at 20 °C.
