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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
The vapour pressure of the test substance was <8.4E-7 Pa at 20 °C (293 K) and <2.2E-6 Pa at 25 °C (298 K).
Key value for chemical safety assessment
- Vapour pressure:
- 0 Pa
- at the temperature of:
- 20 °C
Additional information
The isothermal TGA effusion method was applied for the determination of the vapour pressure of Alkylated Naphthalene. The result showed the weight loss of the test substance at 170 °C, 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 determined to be lower than that of chrysene. Thus, the vapour pressure of the test substance was <8.4E-7 Pa at 20 °C (293 K) and <2.2E-6 Pa at 25 °C (298 K).
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.
