Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Results and discussion

Vapour pressure
Temp.:
20 °C
Vapour pressure:
0 hPa
Remarks on result:
other: extrapolated

Any other information on results incl. tables

experimental data

Temp (°C)/ pressure (hPa)

60.5/ 5.15 E-5

55.5/ 1.93E-05

51.3/ 8.94E-06

47.8/ 5.95E-06

The linear regression of log p vs. 1fT (vapour pressure curve) with:

log P = A + B/T

yields:

Coefficient A = 19.71

Coefficient B (slope) = -8018.99

Degree of precision = 98.8%

With that, the vapour pressure for any other temperature can be calculated (extrapolation).

20°C/ 2.3E-08 hPa; 25°C/ 6.6E-08 hPa
