Description of key information

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

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
127 °C

Additional information

Boiling point 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 C30. At C6 boiling point is around 60°C. At C24 boiling point is around 350°C. Data on olefins with a carbon number range C24 -20 indicates that decomposition occurred before boiling.

The boiling point of oct-2-ene is estimated by EPA EPIWIN Adapted Joback Method as 127 deg C
