Description of key information

Vapour pressure: 671 Pa at 25°C

Key value for chemical safety assessment

Vapour pressure:
671 Pa
at the temperature of:
298 K

Additional information

A solid phase vapour pressure value of 671 Pa at 25°C is reported in a collection of reliable data which has been subject to peer-review and in which the original data sources are traceable (DIPPR 2006). The result is considered to be reliable and is selected as key. It is interpolated from data measured at 297 - 336 K.

Vapour pressures of 4.7 and 11.5 hPa at 25°C

are reported in secondary sources to which reliability could not be assigned. It is not clear whether these are solid- or liquid-phase vapour pressures.
