Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusions:
The vapour pressure of anthracene oil (CCSG composite sample 07) (anthracene oil with < 50 ppm BaP, AOL) at ambient temperatures is below 3 Pa.

Description of key information

The vapour pressure (Vp) of anthracene oil (CCSG composite sample 07) (anthracene oil with < 50 ppm BaP, AOL) is estimated by linear regression from the log(p) over 1/T plot to be 0.011 hPa at 20 °C. At 50 °C and 100 °C, the extrapolated Vp is 0.101 and 1.74 hPa, respectively. A Vp of 14.7 hPa was determined at 151 °C (measured value).

Key value for chemical safety assessment

Vapour pressure:
1.1 Pa
