For the reference substance dibutyphthalate (CAS 84 -74-2) a flash point of 156.5 °C was obtained.

Conclusions:
For heptanoic anhydride a flash point of 147.5 °C was obtained at 1013 hPa.
Executive summary:

According to the testing procedure based on DIN EN 22719 which is the German version of the international standard ISO 2719 a flash point of 147.5 °C was measured at 1013 hPa for the test substance. Heptanoic anhydride was placed in the test vessel of the Pensky-Martens apparatus and heated to the test temperature according to the testing procedure.

Description of key information

For heptanoic anhydride a flash point of 147.5 °C was obtained at 1013 hPa.

Key value for chemical safety assessment

Flash point at 101 325 Pa:
147.5 °C
