Any other information on results incl. tables
The vapour pressure was measured with the dynamic method in the temperature range of 81 °C to 150 °C. The measured vapour pressures at the corresponding temperatures are listed in the table below.
Temperature / °C | Vapour Pressure / hPa |
80.7 | 20.0 |
93.3 | 40.0 |
104.5 | 70.0 |
115.4 | 100.0 |
131.6 | 200.0 |
149.8 | 400.0 |
During the measurement the test item showed a discolouration from yellow to green to black. Therefore it had to be assumed that the item decomposed during the measurement and the measurement was stopped at 150 °C. As the measured vapour pressures showed a good consistency all measured vapour pressures were used for the regression.
The vapour pressure values for 20, 25 and 50 °C were extrapolated, using Antoine constants A, B and C.
Vapour presure results from the regression calculation:
0.317 hPa at 20 °C
0.487 hPa at 25 °C
3.22 hPa at 50 °C
Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
