Description of key information

The vapour pressure of the substance was determined to be 0.0026 hPa at 20 °C, 0.0043 hPa at 25 °C and 0.038 hPa at 50 °C.

Key value for chemical safety assessment

Vapour pressure:
0.003 hPa
at the temperature of:
20 °C

Additional information

A literature review was conducted. In a weight of evidence approach the literature values were evaluated. The Design Institute for Physical Properties (DIPPR) reports the vapour pressure to be 0.0026 hPa at 20 °C, 0.0043 hPa at 25 °C and 0.038 hPa at 50 °C. The Syracuse Research Coperation, Physical Properties Database reports the vapour pressure to be 0.0043 hPa at 25 °C. The GESTIS database reports the vapour pressure to be 0.0011 hPa at 20 °C and the IPCS International Programme on Chemical Safety (IPCS) also reports the vapour pressure to be 0.0043 hPa at 25°C. In addition an elder non-GLP study conducted according the dynamic method determined the vapour pressure to be 0.41 hPa at 98.7 °C.T

All literature sources reported the vapour pressure in the same range. The vapour pressure of 0.026 hPa at 20 °C reported from the Design Institute for Physical Properties (DIPPR) was chosen as key value.
