Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusions:
The boiling point of diphenylamine is reported to be 302 °C

Description of key information

The information is based on different secondary sources with consistent values for boiling point of the substance ranging from 299 - 302 °C.

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
302 °C

Additional information

The key value for the boiling point was chosen according to the most reliable data: the final Risk Assessment Report on Diphenylamine. This value was also found in other sources of literature, and confirmed by the results of the guideline study in the DAR 2007 (boiling point: 298.8°C)
