Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Vapour Pressure Estimations (25 deg C):
Selected VP: 0.0782 mm Hg / 10.4 Pa (Mean of Antoine & Grain methods)

Description of key information

Vapour Pressure: 0.0674 Torr / 0.08986 hPa - Temp: 25°C [Calculated using Advanced Chemistry Development Software V11.02 (1994 -2018 ACD/Labs)]
Vapour Pressure estimation (25 deg C): 0.0782 mm Hg / 0.104 hPa (EPIWEB 4.11: Mean of Antoine & Grain methods)

Key value for chemical safety assessment

Vapour pressure:
0.104 hPa
at the temperature of:
25 °C

Additional information

Both calculated / estimated values are close and estimation is so considered to be reliable.

Highest value: 0.104 hPa
