Description of key information
The reported vapour pressure of the xylene isomers at 25˚C ranges from 0.882 to 1.332 kPa. The vapour pressure of Ethylbenzene at 25˚C was reported to be 1.332 kPa, for m-xylene is 1.106 kPa, for o-xylene is 0.882 kPa and for p-xylene is 1.167 kPa. The mean value of 1.122 kPa was used in this assessment.
Key value for chemical safety assessment
- Vapour pressure:
- 1.122 kPa
- at the temperature of:
- 25 °C
Additional information
Data was taken from Zwolinski and Wilhoit (1971) which is a peer reviewed handbook and so can be considered reliable and suitable for use as the key study for this endpoint. The data are supported by results from the CRC Handbook (Lide 2008), with vapour pressures for m-xylene, o-xylene, p-xylene and ethylbenzene of 1 kPa at 23.4˚C, 1 kPa at 27°C, 1 kPa at 22.4°C and 1 kPa at 21.1°C respectively.
