Description of key information
For 2-chlorobutane a vapour pressure of 20210 Pa at 25 °C has been determined in a weight of evidence approach and is taken forward for hazard and risk assessment.
Key value for chemical safety assessment
- Vapour pressure:
- 20 210 Pa
- at the temperature of:
- 25 °C
Additional information
In standard handbooks and publications the following data for vapour pressure of 2-chlorobutane were identified:
- Dreisbach et al. : 20210 Pa at 25 °C
- Riddich et al. : 20.21 kPa at 25 °C
- SRC database: 157 mm Hg (i.e. 20.9 kPa) at 25 °C
- CRC-handbook: approx. 20 kPa at 25 °C based on values of 10 kPa at 8.5 °C and 100 kPa at 67.9 °C
as a result the value of Dreisbach et al. and Riddick et al. is taken forward for hazard and risk assessment both in the same range as values found in the SRC database and the CRC handbook.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
