Applicant's summary and conclusion

Conclusions:
The Auto-ignition temperature of Tbodiol was determined according to the DIN 51794.

The lowest temperature giving a positive effect was 339°C. The injected volume was 200 µl, the ignition delay was 43 s. At a temperature of 334°C no ignition was observed.

Therefore, after rounding-off to the next-lower multiple of 5°C: auto-ignition temperature of TBODIOL: 335 ± 5°C
Executive summary:

The Auto-ignition temperature of Tbodiol was determined in a SUR BERLIN oven, equipped with a 250 ml glass ignition vessel according to the DIN 51794.

The lowest temperature giving a positive effect was 339°C. The injected volume was 200 µl, the ignition delay was 43 s. At a temperature of 334°C no ignition was observed.

Therefore, after rounding-off to the next-lower multiple of 5°C:

Auto-ignition temperature of TBODIOL: 335±5°C
