Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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