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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Reference
Representative weight loss curves of the test substance and chrysene (one given reference substance) are shown in the anlytical report. The results of the vapour pressure for the test substance at 20 °C and 25 °C are given in the table below.
| Temperature | 20 °C | 25 °C | ||
| Vapour pressure | [Pa] | [mmHg] | [Pa] | [mmHg] |
| <8.4E-7 | <6.3E-9 | <5.8E-7 | <4.3E-9 |
The weight loss of the test substance at 180 °C, 190 °C and 200 °C was lower than the weight loss of chrysene at the same temperatures. According to this, the vapour pressure of the test substance was specified. The weight loss of the test substance at 170 °C was most likley affected by evaporation of impurities of the test substance.
Description of key information
20 °C, VP < 8.4E-7 Pa (= 6.3E-9 mmHg)
25 °C, VP < 5.8E-7 Pa (= 4.3E-9 mmHg)
(OECD 104, effusion method; isothermal thermogravimetry)
Key value for chemical safety assessment
- Vapour pressure:
- 0 Pa
- at the temperature of:
- 20 °C
Additional information
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.
