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.
