Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Experimental range 20-35°C, the regression equation was  log P(Pa) = 14.938 - 4665.4/T(K) 
This gives 0.105 Pa at 20 °C, 0.195 Pa at 25°C.

Key value for chemical safety assessment

Vapour pressure:
0.105 Pa
at the temperature of:
20 °C

Additional information

The regression equation enables to extrapolate vapour pressure values at various process temperatures for inhalative exposure assessment.

If ECETOC-TRA is used, it should be noted that the substance is in the low volatility band (0.01 -500 Pa) up to 108°C and in the medium band (>500 Pa) between 109°C and the decomposition point (~180°C).
