Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 dodecane-12-lactam at 1013 hPa is approximately 348 °C. 

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
348 °C

Additional information

A study was performed with limited documentation. The resulting normal boiling point is part of a vapor pressure curve which is in good agreement with other vapor pressure curves reported in chapter 4.6. It is supported by additional evidence:

- Date and responsibility of the test are reported.

- Test substance: Not documented but certainly of high purity.

- Method: Not documented but certainly comparable to OECD TG 104.

- Dependence on temperature: The whole vapour pressure curve shows normal behaviour and good agreement within itself and with independently determined vapour pressure curves.

- QSAR check: MpBpWin v1.40 from the EPIWIN software suite predicts a value of 361 °C, i.e. the magnitude of the value is reasonable.
