Description of key information
The vapour pressure of 1,1"-isopropylidenebis(ethylferrocene) was determined using the Static method. The test was conducted in accordance with the procedure described in EU Regulation (EC) 440/2008, Annex Part A test A4 and assigned a reliability score of 1 in accordance with the criteria for assessing data quality set forth by Klimisch et al (1997).
The average vapour pressure obtained for 1,1"-isopropylidenebis(ethylferrocene) was determined to be 9 Pa @ 20°C.
Key value for chemical safety assessment
- Vapour pressure:
- 9 Pa
- at the temperature of:
- 20 °C
Additional information
The vapour pressure of 1,1"-isopropylidenebis(ethylferrocene) was determined to be 9 Pa @ 20°C (mean result of 2 runs).
