Description of key information
A vapour pressure of 0.188 and 0.486 mm Hg at 25 °C has been determined for 2-ethylbutyric acid. As the former is derived from experimental data, 0.188 mm Hg (25.065 Pa) at 25 °C is recommended as the key value.
Key value for chemical safety assessment
- Vapour pressure:
- 25.065 Pa
- at the temperature of:
- 25 °C
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
