Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The vapour pressure of pyrrolidine was found to be 64.5 hPa at 20°C.
Key value for chemical safety assessment
- Vapour pressure:
- 64.5 hPa
- at the temperature of:
- 20 °C
Additional information
Data were available from different sources, as summarized in the following table:
20°C 64.5 hPa Gestis
20.7°C 66.61 hPa Beilstein
25°C 83.6 hP aHSDB
28.5°C 100 hPa CRC
30°C 107 hPa Gestis
39°C 171 hPa SAX & LEWIS
40°C 172 hPa Gestis
50°C 260 hPa Gestis
86.2°C 1000 hPa CRC
The value from the Gestis database was selected as a key value, because this was measured at 20 ºC. All values from the different data sources are in a comparable range when the temperature is taken into account.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
