Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

The boiling point of cis,trans,trans-1,5,9-cyclododecatriene is reported as 237.5 °C at 1013 hPa.

Key value for chemical safety assessment

Additional information

The boiling point is supported by a vapor pressure curve as well as by data from other sources that are in reasonable agreement with this vapor pressure curve. The Shell material appears to have a slightly higher vapor pressure and lower boiling point than the Evonik Degussa material, which may be due to differences in isomer composition.
