- Executive summary:
In a study (2015), the auto-ignition temperature of trifluoromethanesulphonic anhydride was determined according to the EC A15 method under GLP conditions.
The test was repeated at different temperatures (from about 100°C to about 600°C) with suitable sampling volumes until the minimum value of the ignition temperature was observed.
The auto-ignition temperature of trifluoromethanesulphonic anhydride was 440 ± 3°C.
