Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Description of key information
The vapour pressure of phenol, mono- & distyrenated, was determined based on OECD TG 104 (dynamic method). The regression equation of the plot log p versus 1/T was used to calculate the vapour pressure at ambient temperatures.
Key value for chemical safety assessment
- Vapour pressure:
- 0.005 Pa
- at the temperature of:
- 20 °C
Additional information
For comparison, the vapour pressure of 2-(1-phenylethyl)phenol, a component of phenol, mono- & distyrenated, was calculated using the modelling software US EPA EPI Suite 4.11, program component MPBPVP (v1.43). Vapour pressure was estimated for a liquid (physical state of phenol, mono- & distyrenated is liquid) by the Modified Grain method. The resulting value (0.0157 Pa, 20°C) is slightly higher than the measured value for phenol, mono & distyrenated (0.0049 Pa, 20°C). But both values are close together and stay clearly below a vapour pressure of 0.1 Pa.
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).
