Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

under Argon
82.28 °C
Vapour pressure:
1 hPa
Remarks on result:
other: lowest value measured
20 °C
Vapour pressure:
0.005 hPa
Remarks on result:
other: extrapolated

The value at 20° C is calculated with the equation: ln (p/bar)= A+B / (C + t/cels)

A= 13.1051; B= -6002.58; C= 218

The Vapour Pressure of the test substance was determined to be 0.005472 hPa at 20° C.

Description of key information
