Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 autoignition temperature for solid biphenyl was determined to be 566 °C

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
566 °C

Additional information

Whereas ECHA Chapter R7a Guidance (2008) indicates that this information requirment may be waived for solid substances having melting point < 160 °C, a reliable measured value of 566 °C is available, and used as the Key Study. Two handbook values of 540 and 570 °C were identified, and used as Supporting Studies. The Key Study value is within 3.2% of the critically-reviewed and accepted value of 540 °C reported in the AIChE DIPPR Database (v5.2.2, 2011); however, a report is not available which documents measurement of this recommended value.
