Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
Auto-ignition temperature (Chemsafe, Dechema) of 2-chlorotoluene: >550 °C
Executive summary:

The auto-ignition temperature of 2-chlorotoluene is reported in the Chemsafe database maintained by PTB (Physikalisch-Technische Bundesanstalt, Braunschweig, Germany), BAM (Bundesanstalt für Materialforschung und –prüfung, Berlin) and DECHEMA (Frankfurt am Main, Germany). Data from PTB (Braunschweig) and BAM (Berlin) must be regarded as reliable chemical safety data. The data set on the auto-ignition temperature for 2-chlorotoluene is marked as "recommended" and verified in terms of reliability and data quality. Information on data origin is made available (data on auto-ignition temperature from Oct. 1989). Accordingly, the data are reliable.
Auto-ignition temperature (Chemsafe, Dechema) of 2-chlorotoluene: >550 °C

Description of key information

The  self-ignition temperature of 1-chloro-2-methylbenzene is above 550 °C (Chemsafe Dechema, 2020).

 

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:

Additional information

The auto-ignition temperature of 2-chlorotoluene is reported in the Chemsafe database maintained by PTB (Physikalisch-Technische Bundesanstalt, Braunschweig, Germany), BAM (Bundesanstalt für Materialforschung und –prüfung, Berlin) and DECHEMA (Frankfurt am Main, Germany). Data from PTB (Braunschweig) and BAM (Berlin) must be regarded as reliable chemical safety data. The data set on the auto-ignition temperature for 2-chlorotoluene is marked as "recommended" and verified in terms of reliability and data quality. Information on data origin is made available (data on auto-ignition temperature from Oct. 1989). Accordingly, the data are reliable.
Auto-ignition temperature (Chemsafe, Dechema) of 2-chlorotoluene: >550 °C


One further reliable result (Rossberg, 2006; >500 °C) is in support of this value.
