Result: 9 Pa at 20°C (mean of runs 1 & 2)

Conclusions:
The average vapour pressure obtained for 1,1"-isopropylidenebis(ethylferrocene) was determined to be 9 Pa @ 20°C.
Executive summary:

The vapour pressure of 1,1"-isopropylidenebis(ethylferrocene) was determined by the Static method, conducted in accordance with the procedure described in EU Regulation (EC) 440/2008, Annex Part A test A4.

Average vapour pressure from 2 runs was found to be 9 Pa at 20 degrees C.

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.
