Description of key information
Vapour pressure: 2.01 hPa at 30.6°C (measured)
Key value for chemical safety assessment
- Vapour pressure:
- 2.01 hPa
- at the temperature of:
- 30.6 °C
Additional information
The vapour pressure was experimentally determined by a dynamic method (BASF, 1972). Nine different temperature levels were used in this test (~ 30°C - ~ 160 °C).
