Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: 265-099-7 | CAS number: 64741-98-6 A complex combination of hydrocarbons obtained as the extract from a solvent extraction process. It consists predominantly of aromatic hydrocarbons having carbon numbers predominantly in the range of C7 through C12 and boiling in the range of approximately 90°C to 220°C (194°F to 428°F).

Description of key information
The reported vapour pressure of toluene is 0.448 PSI (3088.9Pa) at 70°F (21.1°C) and 0.599 PSI (4130.0Pa) at 80°F (26.6°C).
Key value for chemical safety assessment
- Vapour pressure:
- 3 089 Pa
- at the temperature of:
- 21.1 °C
Additional information
The handbook of vapour pressure and heats of vaporization of hydrocarbons and related compounds (Zwolinski and Wilhoit, 1971) is a peer reviewed handbook and is considered reliable and suitable for use as the key study for this endpoint. In addition, this vapour pressure is similar to the vapour pressure reported in the EU RAR.
The supporting study (CRC, 2008) is also a peer reviewed handbook and supports the value reported in the key study, giving a vapour pressure of 1 kPa at 1.5°C and 10 kPa at 45.2°C.
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.
