Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The test item did not change in appearance under test conditions.

A total of 10 runs were completed for the main sequence. Vapour pressure equilibrium was not reached for runs 1-3 and so the results of these runs were not reported.

Equilibrium was reached over the final 7 runs, therefore the results of runs 4-10 were used to calculate the vapour pressure.

Some of the runs required data points to be removed due to being erroneous. Plots of log10 (Vapour pressure) against reciprocial temperature (1/K) with and without the erroneous results were provided in the report.

Conclusions:
The vapour pressure of the test item has been determined to be 1.5 x 10-8 Pa at 25 °C using a procedure designed to be compatible with Method A.4 Vapour Pressure of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 104 of the OECD Guidelines for Testing of Chemicals, 23 March 2006.
Executive summary:

The vapour pressure of the test item has been determined to be 1.5 x 10-8 Pa at 25 °C using a procedure designed to be compatible with Method A.4 Vapour Pressure of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 104 of the OECD Guidelines for Testing of Chemicals, 23 March 2006.
