Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

255 °C

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
255 °C

Additional information

Data from the Physicalisch-Technische Bundersanstalt-Arbeitsgruppe determined the autoiginition temperature of trimethyl orthoformate to be 255°C. Limited details were provided.

A secondary source of information is also available (Draeger Safety 2007), which also reports the auto ignition temperature as 255°C. Whilst there are obvious limitations to both data sources the value reported is far in excess of any safe handling conditions required for trimethyl orthoformate given the relatively low boiling point and low flash point (9°C).
