Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
293 hPa at 20°C (366 hPa at 25°C)
Key value for chemical safety assessment
Additional information
1. European Union Risk Assessment Report of Acrolein (EU, 2001)
Vapor pressure: 293 hPa at 20°C
2. Agreement with further international Reports and Studies published after finalisation of the EU Risk Assessment Report 2001
US ATSDR (2007): vapor pressure: 274 mm Hg at 25°C (366 hPa)
WHO (2002): vapor pressure: 293-365 hPa at 20°C ( remark: both vapor pressure values are cited in the same reference, however, vapor pressure at 20°C is reported to be 293 hPa whereas at 25°C the vapor pressure is stated to be 366 hPa)
3. Substantial disagreements in comparison to further international Reports to European Union Risk Assessment Report 2001
The higher vapor pressure value (365 hPa at 20°C) cited in WHO (2002) might correspond to 25°C.
4. Additional aspects in further international Reports
None
5. Additional information in newer Studies, not included in the European Union Risk Assessment Report 2001 or further cited international reports
None
6. Conclusions
The vapor pressure of acrolein is 293 hPa at 20°C and 366 hPa at 25°C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
