Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 reaction mass of cyclododecanol and cyclododecanone has a vapor pressure between 0.52 Pa and 0.71 Pa at 20 °C, depending on the cyclododecanol / cyclododecanone ratio.
Key value for chemical safety assessment
Additional information
The vapor pressure of cyclododecanol was measured at temperatures between 131.5 °C and 278.0 °C (normal boiling point) leading to a regular vapor pressure curve. A value of 0.52 Pa at 20 °C was obtained by extrapolation. The vapor pressure of cyclododecanone was measured at temperatures between 135.6 and 290.8 °C with the static method leading to a regular vapor pressure curve. A value of 0.71 Pa at 20 °C was obtained by extrapolation. The reaction mass of cyclododecanol and cyclododecanone therefore has a vapor pressure between 0.52 Pa and 0.71 Pa at 20°C, depending on the cyclododecanol / cyclododecanone ratio. Due to the structural similarity of the constituents, no significant irregularities in vaporization behavior are expected.
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.
