Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 vapor pressure of cis,trans,trans-1,5,9-cyclododecatriene was measured at temperatures between 104 and 237.5 °C leading to a regular vapor pressure curve. Experimental details have not been reported. A value of 0.1222 hPa at 20 °C was obtained by least squares-fit of a Clausius Clapeyron curve and extrapolation.
Key value for chemical safety assessment
- Vapour pressure:
- 12 Pa
- at the temperature of:
- 293.15 K
Additional information
Information from two independent sources is available and shows good agreement. 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 cis/trans isomer composition.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
