Type:
relative density
Density:
0.72
Temp.:
20 °C
Conclusions:
The relative density of caprylene batch 50906 measured using a hydrometer was 0.722. Based on possible batch variance and experimental error it is recommended to report the density for caprylene to 2 decimal places hence 0.72.

Description of key information

A trend of increasing density with increasing carbon number is seen for category members.

Key value for chemical safety assessment

Relative density at 20C:
0.72

Additional information

The measured relative density of Caprylene (78% Oct-2 -ene) was 0.72 at 20°C

Density increases with increasing carbon number across the category, with a very similar trend for both the alpha olefins and olefins. Data is available for category members with carbon numbers of C6 to C28. At C6 density is around 0.67. At C28 boiling point is around 0.8.
