Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 pressures of representative compounds of the test substance were estimated to be:
Structure A: 1.96 x 10-7 Pa at 25°C
Structure B: 4.95 x 10-7 Pa at 25°C
Structure C: 5.44 x 10-7 Pa at 25°C
Structure D: 1.40 x 10-6 Pa at 25°C
These are based on the boiling points calculated and using the Modified Watson Correlation.
The test substance is a complex mixture of many different compounds with different vapour
pressures. The determination of one specific vapour pressure for the test substance is therefore not
possible. Higher vapour pressures are also probable.
Reference
The boiling points of the representative components of the test material were calculated to be between 557 and 595 deg. C using Meissner's method.
The test material is a complex mixture of components with different vapour pressures. Hence the determination of one specific vapour pressure is not possible.

The test substance is a complex mixture of many different compounds with different vapour pressures. The determination of one specific vapour pressure for the test substance is therefore not possible. Higher vapour pressures are also probable.

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.
